Azure Web Service Getting Timeout

Question

Hi team, we have a web app that gives random timeout errors. Since the error does not occur constantly, it is not repreduced. 3 out of every 100 submissions do not receive a response, the others work successfully. Additionally, we see faulty requests on Azure only as traces in the log. The parameters and duration match completely, but the request log does not appear. When the same request is triggered again, there is no problem in sending.

By the way, we turn on the ALWAYS ON option in Azure web app

@Ali Akarsu , Apologies for the delayed response from over the weekend. I understand that the issue happens randomly.

You may leverage App Service diagnostics from Azure Portal> Navigate to your App Service app in the Azure Portal. (screenshot below). https://learn.microsoft.com/azure/app-service/overview-diagnostics

Also, review Enable and review logs to fetch more details about the error.

To isolate the issue, scale-up your App Service and observe the behavior of the app.
