What are the urls required to unblock through firewall in corporate network for accessing for Google Translate API (Advanced Version)?
Right now unblocked are:
*.googleapis.com and accounts.google.com
But still I get below error:

Settings must be of the form "name=value". at Microsoft.Azure.Storage.CloudStorageAccount when running Azure webjob timer trigger
You haven't added the Storage Account Connection String in appsettings.json file.
Create a Storage Account and copy the Connection String from Access Keys = >Connection string.
Add a new file appsettings.json and add the below line
AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=StorageAccName;AccountKey=****==;EndpointSuffix=core.windows.net"
Thanks #christiandersen and Coding Canvas for the explanation.
For the Web Job to run the timer-trigger we need to set it as a Scheduled Jobs.
Your settings.json must contain the below settings.
{
"schedule":"0 */15 * * * *",
"is_singleton":true
}
This setting is to specify the CRON expression/ time span which specifies the web job to trigger.
I am running a fairly basic Azure IoT C# module. Initially, it all worked fine. However, when I set up X.509 certificates for the edge hub, I've been getting module authentication errors as follows. There seems to be some dependence on using Tcp_only or Websocket_only options of the AMQP/MQTT protocols (where the latter does not throw the exception), but this is not consistent across modules.
The offending lines of code are below
..
// Open a connection to the Edge runtime
ioTHubModuleClient = await ModuleClient.CreateFromEnvironmentAsync(settings);
await ioTHubModuleClient.OpenAsync();
The error message is below. Essentially the await times out because authentication is not complete. Far as I know, authentication is derived directly from the iot edge runtime, so not sure why it was specifically trying to authenticate or erroring out...
Unhandled Exception: System.AggregateException: One or more errors

I ran the Resource Monitor from the Task Manager Performance Tab and can see that there are 2 entries on Listening Ports for 8080.
Both have Image=System, PID=4, IPv6 unspecified, Protocol TCP, Firewall Status Not allowed, not restricted
I am new to Listening Ports, how do I get the code working?
When faced with error: "Failed to listen on prefix 'http://someURL:somePortNo/' because it conflicts with an existing registration on the machine." It is not really necessary that there is an application actively listening on that port - thus output of Netstat -abno may not always help. If the already registered application is running it can help you narrow down to which application is causing the issue by looking at the info Netstat provides.
However, you will get this error even after the application in question is stopped since the error indicates a registration. The correct diagnostic command therefore is:
netsh http show urlacl
We need to examine the output and check whether any of the listed reserved URLs is configured to listen on the specific port your application is trying to use. You need to note the value of the "Reserved URL" field for that specific application. You will need it later for deleting the registration which is causing the error.
Uninstalling that specific application - assuming their uninstall procedure does include an un-registration - may resolve the problem. Alternatively you could take a more direct and precise approach of using the command for deleting a URL reservation:
(Note that if the conflict is legitimate, it may be better to reconfigure your application to listen on a different port instead.)
netsh http delete urlacl url=<value of "Reserved URL" in the output of netsh http show urlacl>
When the command works you will see output: URL reservation successfully deleted.
Upon running netsh http show urlacl a second time you will now see that the url registration is indeed gone. And now running your application should not result in the error you were seeing earlier.
I was able to solve the problem by uninstalling several programs.
Unfortunately I did not test after each, so I don't know which one it was.
They included Dropbox, Goto Assist, Goto Meeting and a winforms application
I had the same issue, and it was a silly fix. I had other console apps open that was using the same port number, so after I have closed all the console apps, I was able to run and did not get this error.
I had the same error in Visual Studio which was kind enough to tell me which port was wrong. I then ran this command in an Administrator Command Prompt:
netsh http delete urlacl url=http://+:44308/
Note : It is important to remember to final slash. Otherwise you will get an error.
I am scratching my head over a peculiar problem that seems to work on IE and Chrome.
We have a custom passive STS which serves a RP. All is well till i authenticate via my custom authentication service and then STS returns token which i can see in my temp folder. The POST operation which then sends the SAML 1.0 token hangs and silently dies instead of getting back the FedAuth cookie which would normally redirect me the RP
Note : RP and IP are hosted on web server that is behind a reverse proxy server (Nginx). Reverse proxy is hosted over SSL and all traffic to and fro proxy server and webserver is non SSL
The following get logged on the webserver

I dont understand why just for FF i get this problem. Is there a limitation on the size of the content that is sent in the header for FF?
Another question is : I have installed two different certificates one at proxy server (SSL)and one at webserver(STS) to signing the token. Can i use the same certificate? Should i?
According to the top voted answer on the question Can HTTP headers be too big for a browser, Firefox does have the lowest individual header-size (or at least did back in FF3.6). The accepted answer may help you though as you've mentioned you're behind a proxy.
In my application, I am using a code piece to send a content to a web proxy with a URL with an interval of 2 seconds between each post. The message to post in the below code is given as static string, but will be dynamic in the original application code.
for (ic = 0; ic < 30; ic++)
{
using(HttpClient httpClient = new HttpClient())
{
Encoder encoder = new Encoder(); //This is a class which we created
AuthorizationHeaders authorizationHeaders = encoder.getAuthorization(PARTNER_ID, PARTNER_KEY, URL, "POST", "application/xml");
httpClient.DefaultHeaders.Add("Accept", "*/*");
httpClient.DefaultHeaders.Add("Authorization", authorizationHeaders.getAuthorizationHeader());
httpClient.DefaultHeaders.Add("Expires", authorizationHeaders.getExpiresHeader());
httpClient.DefaultHeaders.Add("origPartnerId", "MyWebSite");
httpClient.DefaultHeaders.Add("appId", "440");
httpClient.DefaultHeaders.Add("Content-Type", "application/xml");
string inputUrl = ConfigurationManager.AppSettings["url"];
String detailRequest = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Message><Details><Name>Bob</Name><Age>45</Age></Details></Message>";
var content = HttpContent.Create(detailRequest, Encoding.UTF8, "application/xml");
response = httpClient.Post(inputUrl, content).EnsureStatusIsSuccessful();
Thread.Sleep(2000);
}
}
But I am getting the below exception when contacting the proxy. I am not getting it all the time, the message does go through some time, but eventually, this exception comes.

But this proxy is just a redirection to another one. So I tried directly to that one also. There, I was able to do this 2 or 3 times successfully but it generated another exception after that. I tried again, but this time, the exception came for the first try itself. I waited for some time and then tried again, and surprisingly, it did go through 2 or 3 times and then again the exception came. The exception that I am getting this time is different and it is this...

The proxy rules of some companies will cause problems with POST requests.
GET requests work fine. Check that your OS proxy setting is disabled.
Windows 7: Control Panel > Internet Options > Connections (Tab).
Then click on the "LAN settings" button and then uncheck "Use a proxy server for your LAN".
Alternatively, try and get your Network Admins to add the connection that you are using to the exclusion list.
