Description
Invalid client issue on auth screen pops-up now and then, investigate what the culprit is.
Some context: https://forum.cortezaproject.org/t/invalid-client-not-found-agian/981
Cause:
This happens due to opening too many (>2) new tabs simultaneously. since all the request uses the same auth_session to authenticate, due to that once auth_session verifies clientID is removed from it, due to that auth flow fails for the others and result in invalid clientID(empty).
