I am trying to access my localhost of rails running project on my mobile device.
This is how I am trying.
http://ip:3000
But it says the webpage is not available.
I tried with another port as well and It doesn't work even there?
What's wrong here? I use to check earlier this way.
Please guide
Try running this code below to your server:
rails s -b 0.0.0.0
This worked for me!
Just give:
ip = your phone's ip address
(Check it in connection information if you are running this on Ubuntu)
ip:3000/your_page if you do not have mapped your root to some page.
Else ip:3000 will work if you have mapped root to some page.
Try it in Chrome and see as it doesn't need any http or https it automatically selects the required one.
Here is how I did it
Put both your computer and phone on the same wifi network
rails s -b 0.0.0.0
routerlogin.net (or however you access your router it will say on the back of router)
get attached devices to the router. Note your computers ip. Mine was 10.0.0.20
on phone go to 10.0.0.20:3000 (but use the ip for your computer from step 4)
I'm trying to debug my application but any URLs which contain localhost (I've tried IIS Express, Local IIS, a simple Node server, and a Python development server) are redirected to the IIS welcome screen.
Examples:
localhost:xxxx/MyController
localhost:xxxx/SomeFolder/SomeFile.html
localhost/MyApp/MyController
localhost/MyApp/SomeFolder/SomeFile.html
The URL changes from the full url to my external IP address (i.e., URL changes from localhost:xxxx/MyController to simply XX.XX.XX.XX)
I just tried launching with a brand new ASP.NET "Empty Web Site," just loading the index.html file, and same situation.
There are no entries in my hosts file and it appears that this is only happening in Chrome. Any ideas?
This works in php, so it may help you with ASP:
Run Notepad as administrator
Open C:\Windows\System32\drivers\etc\hosts file
add the following line to hosts file
127.0.0.1:123 yourserver.com
Save
Run command prompt using CMD in run or type it in start menu
Type this command and hit enter
ipconfig /flushdns
Close
go to yourserver.com
I hope this help you. Again, this works fine with PHP.
It sounds like your DNS is resolving the localhost hostname. If you're using your ISP's DNS, this may happen. You could change the DNS to Google's Public DNS. By pointing the DNS server to IP's 8.8.8.8 and 8.8.4.4. See the link for details on how to configure your computer.
I have TFS 2010 set up on TESTServer.
If I am on the server (logged in as administrator) I can access the web portal for TFS using the following
http://TESTServer:8080/tfs/web/
but when I am on my own computer still in the same network, when I try the same URL, I get challenged for a username and password. Even when I enter the administrator details, it does not accept them.
Also I tried the following
http://TESTServer:8080/services/v1.0/ServerStatus.asmx?op=CheckAuthentication
Which says the resource can not be found
* update***
I got it to work with the IP address... but if I ping the name it gets the correct IP address??
Any ideas?
Thanks
Since you cannot connect to http://TFSSERVER:8080/services/v1.0/ServerStatus.asmx?op=CheckAuthentication it could be that you have incorrect proxy settings in your organization. Could it be the proxy settings have changed?
Have you checked your host file for any entries regarding your TFS server?
Can you open a telnet session to port 8080 on your TFS Server?
Grant Holliday wrote a couple of steps you can do to troubleshoot TFS connection issues.
I'm creating an iOS app that uses a Rails API backend on Heroku. Periodically (one every 20 API calls), heroku cannot be found. The following NSError is returned:
Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found." UserInfo=0x755ce00 {NSErrorFailingURLStringKey=https://xxx.herokuapp.com/api/v1/matchups, NSErrorFailingURLKey=https://xxx.herokuapp.com/api/v1/matchups, NSLocalizedDescription=A server with the specified hostname could not be found., NSUnderlyingError=0x71ca730 "A server with the specified hostname could not be found."
Seems like a DNS issue on the network to which your iPhone/iPad is connected. To be sure, try any of the following:
1) Change your host name to an IP address instead of a string hostname, and add a Host: header to the HTTP request.
2) If (1) is hard, set your iPhone's DNS to a PC on your LAN, and install a DNS server on that PC, and serve at least that specific address directly from the PC (don't recurse for that domain).
It looks like you are being hit by a Dyno sleep behaviour. Please check this documentation, specially the section Dyno sleeping and make sure you understand it.
Also there are several ways to keep the app on, like pinging the site regularly.
Another option is DNS, create an Ad-Hoc network on your computer and connect your iphone to that network. Use wireshark to make a network capture and analyse the DNS and HTTP responses.
Your url = https://xxx.herokuapp.com/api/v1/matchups
Did you explicitly specify your subdomain xxx with your domain provider to direct to your server IP?
If not, try add a new A record with your subdomain xxx point to your server IP.
Hope that helps.
I've been experimenting with EC2 for a couple days and have been banging my head against simply even being able to access the sample site I've hosted. The stack is Rails 3.1.3 with Thin and Nginx.
I've tried several different configurations and finally ended up running the Nginx auto install script, which does return a webpage when I do a curl http://ec2-107-20-143-179.compute-1.amazonaws.com/. However, when I point my browser there, it hangs forever before saying the page cannot be found.
I have assigned an Elastic IP address, and I've enabled HTTP access via port 80.
I don't much experience with the sysadmin side and I'm basically stumped at this point. Any advice would be greatly appreciated.
Did you enable the http port to all ips? That would be done by going to:
EC2 -> Security Group -> Default (or your custome one) -> Inbound
And then Create a new rule for HTTP and as a source, you should assign: 0.0.0.0/0
That should do it.
Think the AWS UI may have been updated but based on Deleteman's answer
Login to EC2 Dashboard
Instances > Instances
Actions dropdown > Networking > Change security groups
You will probably see that you only have launch-wizard-1 allowed which for me only allowed SSH access on port 22
So as Deleteman mentions, you may need to alter your security groups...
Login to EC2 Dashboard
Network and Security > Security Groups
Remove any filters that may be in the search box to show all groups
Personally I edited the default VPC security group as this is a sandbox for me, I imagine you'll want to create a security group for your project
Select the security group checkbox, select actions dropdown and click "edit the inbound rules", I used the following inbound rules just to be sure it was all working
When you revisit Instances > Instances > Description, you should see the security groups and the rules
Once you are happy it's working I would probably replace all traffic with HTTP and HTTPS if that's all that is needed
I was here earlier looking for a solution to a similar problem I was having. It turns out in my case that the EC2 instance also had its own firewall running in addition to the EC2 security group. The command 'system-config-firewall' let me get in to open the ports. Ports 80 (HTTP) and 3306 (MySQL) were not open by default. 22 (SSH) was open. I also had to do 'yum install system-config-firewall'.
To summarize, my solution was:
> yum install system-config-firewall
> system-config-firewall
This answer is for the newbies who have no idea what they are doing with an ec2 instance.
I was having the same problem and tried all the Security Group fixes to no avail.
As it turns out, I needed to turn on my server from the command line.
sudo service httpd start
Sometimes it's dark, not because a fuse blew, but because you didn't flick the switch.
I face the same issue multiple times with the ubuntu EC2 instance and here I am adding all the methods which helped me in fixing the issue in different situations.
Make sure you are accessing the "Public IPv4 DNS" or "Public IPv4 address" or "Elastic IP addresses" from the browser.
Check whether port 80 is open or not.
Here you can see that port 80 is not open in Inbound rules. So let's open port 80 first. For this click on the security tab and you can see the Security groups open this new tab
Now you have to edit inbound rules.
Click at add rule
Then select type HTTP and source AnyWhere and save it.
Similarly, you do HTTPS also.
Check the browser URL if HTTPS is not enabled and if we try to access from browser default it might be HTTPS if so please make it HTTP and try again.
Edit Network ACL. Select the Networking tab and open Subnet ID in a new window.
From Subent Id open Network ACL in the new window
Now edit inbound rules.
For me, It was as simple as just changing the url from https://my-site to http://my-site on my browser. (This solution only applies to people who are still able to SSH onto the ec2 instance but cannot connect via browser)
I was also struggling with same problem had created security group as well, but did not applied to the instance. Just create new rule for http. And apply from right click instance and choose security group and assign it.
Octopus' answer was the correct one for me, except for a Windows machine.
I needed to go to the Windows Firewall, was blocking all traffic out of the VM if it didn't match a rule. Port 80 wasn't enabled in a rule, so I merely had to add one.
Very stupid of me as I forgot to install web server (HTTP server) because of which my ec2 instance public IP was not working. Answering this question as this can also be one of the reason which one should not miss as I did.
You can install either,
nginx:
sudo apt-get install nginx
apache2:
sudo apt-get install apache2
I have encountered a quite similar situation when I tried to run my go app on EC2. If you cannot see an appropriate message or result on your browser even though you:
can get a response well using curl,
finished configuring the Security Group properly
open pen inbound traffic for 80, 443 for the world or for your IP address and
open inbound traffic for 22; and
open inbound traffic for a port that you use (like 8080, 4343, etc.)), and;
run your app to accept a connection from the outside (npm app.js, go run . etc.)
Make sure that you entered http://ec2-..., instead of https://ec2-... on your browser. You cannot connect to the server with https:// even though you open 443 port, unless you already configured ssh certificate. Entering the full address with http protocol, without omitting it, may solve the problem.
I had the same issue, been racking my brain bad since I have no experience with Ubuntu or linux. The answer from Parag fixed it.

The best way is to edit your security inbound rules. Please refer to below snap.
I know this is a very old thread but faced this issue with many services recently. When you are running any application server like Puma or Unicorn over port example 3000, without having a Load Balancer or Proxy like Nginx frontend it. You have to follow two steps:
Bind the service to 0.0.0.0/3000 and not 127.0.0.1/3000.(This will
leave your service open and accessible by anybody on the internet,
that is were step 2 comes into picture).
In AWS security group now allow port 3000 for 0.0.0.0 if you want it
be access by anybody over the internet or add VPN or your network IP
to allow it only for you and you team.
My problem was the browser.
Chrome works; Firefox DOES NOT work.
Here are the steps that you can follow and when you check both of these, chances are that they will work for sure.
Make sure that you're using http:// in the browser instead of https:// on the IP and amazon IPV4 public DNS (It comes in some form like http://ec2-some-ip-address-here.region.compute.amazonaws.com)
Click on the instance id and scroll down,
go to the security tab,
click on security group it will look like this [![enter image description here][1]][1]
Click on edit inbound rules
Add this
For type- choose HTTP
Source - choose anywhere or anywhere ipv4
and click save and you're done.
Combination of these two should work fine.
While we opened inbounds rules http and https it goes automatically with either one http or https so follow below:
Make sure that you entered http://ec2-..., instead of https://ec2-... on your browser.
For me, I needed to setup ufw and allow it on my EC2insttance. I did so with this command sudo ufw app info "WWW Full"
In my case, it's because I access the public IP with HTTPS, so remmeber to remove 's' in the browser. So stupid!
it may solve by putting http instead of https in browser address
My Windows Ec2 instance was not accessible when I tried to access the public IP from the browser. After checking all the above, I had to update the Windows (Defender) Firewall setting which was blocking the incoming traffic.
