We have auth0 implemented with our AngularJS application. Unfortunately, seems like some of our clients have problem having access to our system once in a while.
The problem is that they face 502 bad gateway error after login in done and they are back to call back URL.
I have check the cookies and the reason for 502 error is too many Auth0 generated cookies.
Problem appears once in a while and will be fixed by clearing the cache and cookies.
Example generated cookies are included blow.
