Sometimes login fails on production env

[omranlm]

Describe the bug Sometimes the log in doesn't redirect properly to the home page. It gets stuck in the authentication page

To Reproduce Steps to reproduce the behavior:

1. Go to fAIr any page
2. Click on sign out if you are already signed in
3. Make sure you are signed already in your OSM account using the same browser
4. Click on sign in and if you get a blank page, try to refresh the page .. at some point you will get logged in !

Expected behavior Redirect works properly after sign in click

Screenshots Recorded the scenario https://drive.google.com/file/d/1axQXhFqWC0KLSOCxn09wkqhrciAjquwp/view?usp=sharing

• Browser chrome,==
