Hi I'm learning ruby on rails but all of a sudden localhost/3000 is not working, it was working fine moments ago. I'm using windows 8 and my ruby version is 2.2.4 and rails version is 4.2.6
Rails server is running but localhost/300 is not loading in browser. Help please.
rails server
browser
You're using /3000 instead of :3000. You need http://localhost:3000 which connects to localhost using port 3000.
It does actually indicate the correct URL in your console output.
You have to run the server on a port and it is 3000 so the address should be http://localhost:3000 instead of http://localhost/3000.
Ports are followed by : in the url

I have installed docker on Ubuntu-21.04 and I'm trying to run apache/nifi on it. I am using this command: docker run --name nifi -dp 8443:8443 apache/nifi. From the logs all seems fine:
Generated Username [24a06eea-579f-443a-ad81-b9fe95d46bd3]
Generated Password [9D3NKqhLElChcXHw0jzfO/wkT8yOV+uV]
2022-03-24 15:39:27,726 INFO [main] org.apache.nifi.web.server.JettyServer NiFi has started. The UI is available at the following URLs:
2022-03-24 15:39:27,726 INFO [main] org.apache.nifi.web.server.JettyServer https://a8917820086b:8443/nifi
The entire logs are here
But if i go at localhost:8443 I see this:
on firefox
and on chrome.
I don't know why I can't access to the UI of Nifi.
I have done all of this exactly on windows 10 and it works. Someone can help me? Thanks in advance.
You need to go to https://localhost:8443 not http://localhost:8443. By default NiFi is now secured with TLS, but 8443 is not the standard HTTPS port, thus it does not automatically redirect you to HTTPS if you only enter localhost

I have two servers both of them running on localhost. On port 3000 it's a NextJs development server and on port 4000 i am running a Rails Api only server. I have not added any extra libraries or packages. I have a api endpoint like http://localhost:4000/products. And i have a fetch request from a NextJs page component's getServerSideProps function. I want to see how CORS works between these two servers. In development mode they are on the same domain localhost. But in production they will be different. How can i test CORS while both of the servers running on localhost?
In your /etc/hosts you can change the domain from localhost:4000 to api.example.localhost and keep the next one running in the same environment

I have a nodejs client that uses bramqp for connecting to RabbitMQ server. My client can connect to a Rabbit MQ server in localhost and works well. But it's unable to connect to a remote RabbitMQ server on other machine. I opened port 5672 in the remote server, so I think that the problem is in the configuration of rabbitMQ server. How can I solve this problem?
The problem seems the new rabbitmq access control policy
Please read this post:
Can't access RabbitMQ web management interface after fresh install

I ran the Rails server and, when trying to view my page on my localhost, I see this error:
Could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?
The weird thing is that a week ago this page was displaying and now it is not, so I don't understand what changed.
The 5432 port error is probably indicating that Rails is trying to connect to a PostgreSQL database that hasn't yet been created or isn't running.
Check to make sure your config\database.yml file is accurate and run the following command:
bundle exec rake db:create
