1. We have tried to extend the session time out to 30mins
2. Tried to scale up the Azure speed when this error occurs

Answer 1

Please see the following Microsoft Blog;

Did Your Session Really Expire?

and verify the followings stated in the above blog:

1. Your session really did expire
2. The session isn’t available to the server handling the request
3. Cookies are disabled on the client

If your answer to my comment "Is your session InProc? Do you use a web farm?" above is Yes, consider item 2 first.
