Could you please show me how to manipulate Azure connection idle timeout?
Now I am using Azure VM and host my web application in IIS. My App calls rest service from the outside network and it takes 5-10 minutes to get the response back. I have read that Azure will close any connection if there is no response more than 4 minutes. I tried to set idle timeout to 30 minutes from the Azure portal public IP configuration, but it doesn't fix the issue.

I'm having an issue with the timeout of my application gateway waf v2.
I set the timeout to 220 sec as showed in the following picture
but im getting a 504 gateway timeout of a particular request at 100 seconds.
Do I need to have any other consideration for make this timeout possible?
[UPDATE]
The error is a 504.0 Gateway timeout.
If I force this error, putting a wait statement on my SP, the error is just a 504 Azure Gateway Timeout
Thanks in advance
Most probably this is happening from your app service and not from the gateway.
Since you are getting a timeout at 100 sec, this may be from the default http timeout. you can check the application gateway request timeout is set correctly by the below .
az network application-gateway show --resource-group <replace with your resource group> --name <replace with your application gateway name> --query 'backendHttpSettingsCollection[].{name: name, reque stTimeout: requestTimeout}'
if this is coming out as expected (230 sec), then you need to see your app service.
For example, if your backend is configured in azure app services, the typical deployment will be based on IIS and the default connection timeout is 2 minutes.
You can override the behavior of the app service. If it is in azure app service, you can use XDT to change the connection timeout attribute of weblimit .
If it is a.NET application that serves the request that you have mentioned and uses HTTP client, then the default timeout is 100sec. You should set a request timeout value that is greater than your application gateway
HttpClient httpClient = new HttpClient();
httpClient.Timeout = TimeSpan.FromMinutes(10);

The error 504 gateway timeout usually occurs when one or more servers could not complete the request within the allotted time and does not receive a timely response from gateway.
To verify if the backend is taking time for the response, you can enable diagnostic logs on application gateway.
By this you can find access logs for the time taken by backend for the response.
Using these logs, you can view Application Gateway access patterns and analyze important information.
Please check whether your domain is proxied via CloudFlare as #Ked Mardemootoo commented.
Please note that:
As your connections are getting dropped at less than the request time out seconds set, you need to find which connection is triggered.
To resolve the issue, please contact Azure Support.

I have a little problem while using hybrid connections in Azure to connect a local resource. I installed the connection manager successfully and established a connection to the on premise resource, everything works fine...
But after around 20 minutes the connection gets lost until I restart the azure hybrid connection service on the on premise server.
The AppService is connected to more than one server and all other connections work well. Does anyone have an idea how to fix this problem and establish a stable connection?
We encountered similar issues with Azure endpoints. We resolved it by having a scheduled message sent to the local BizTalk web services every 3 minutes to keep it alive.
I have an Azure VM configured with IIS role and a web service application installed in it. This web service application makes a call to an Azure SQL Database.
When I first configured the servers, the connection was pretty good (1-2 seconds response time), in the past 2 days the connection to the server has been very slow (15-20 seconds response time when it doesn't timeout). Is there anything I should be aware of int he Azure servers to make the connection faster?
I am evaluating Azure VM with MSDN subscription. I created a few server 2012 VMs. However, apparently Azure timeout the connections idle after a few minutes.
How to extend the timeout period at the Azure side?
This might be bit late , i update the response anyways . ITs possible to increate the time out by updating Keep Alive setting in the registry. This setting causes to send “heartbeat” packets to connected clients every so often. With this setting the connection can be prolonged.
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal
Services] "KeepAliveEnable"=dword:00000001
"KeepAliveInterval"=dword:00000001
I have an MVC 4 website using a WCF service. When I deploy to Windows Azure using the VS 2012 publish wizard, I get this error:
10:13:19 AM - The HTTP request to 'https://management.core.windows.net/42d4257b-5f38-400d-aac5-2e7acee9597d/services/hostedservices/myapp?embed-detail=true' has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout.
After cleaning the project and publishing a few times, the error goes away. What am I doing wrong?
Whenever you start publish process from VS machine, a SSL tunnel is established first and once the tunnel is created, the package is transferred from your machine to Windows Azure Portal first. After the upload is completed, you will see the result notifications are posted back to Publish result windows and that is how it happens.
In your case, the time to build the SSL tunnel doe secure package transfer is longer then normal, this could be because of network latency between your machine and the Windows Azure Management Portal. For security reason the time to create the tunnel smaller windows and if the connection is not created, the retry cycle starts the process again and even if that fails you are greeted with the failure message. This could be caused by excessive traffic on either side or both sides. So this is mainly a networking related issue rather then specific to Windows Azure as after some time successive tries, you could upload your package.
In such failure/situation, you can run network capture utilities i.e netmon, wireshark, and see the time taken during failure and success to see the different in various transfer. This will help you to understand the underlying delaying issues.
Try to update your roles diagnostics

then update your storage credentials because it may be expired.
