I have some function apps that have been running smoothly for several months (Python 3.8, Linux, Consumption plan, West Europe). All of them has different types of functions, durable, http and timer triggers. After I deployed a new build (to two of them) using Visual Studio Code, my functions started to timeout, the changes I made I don't think have anything to do with it.
@PlamenTsanov-8257 I will suggest you to verify the application setting in your azure function if it is the same as your local.setting.json.
The issue might also be caused due to the storage account used for your function that is either not accessible or the storage connection string that you are using being changed or incorrect. Please verify the same.
Alternatively, I will also suggest you to review Azure Functions diagnostics to find the root cause of timeout. If you have enabled application insights then you can also review your application insights logs for your function to know more about the full exception trace/error message that is causing timeout errors.
