CAS not working after upgrade to 6.2.1


Server Setup Information

  • Version of Rocket.Chat Server: 6.2.1
  • Operating System:
  • Deployment Method: snap
  • Number of Running Instances: 1
  • OS : Ubuntu 20.04.5 LTS

After the automatic update of rocketchat to version 6.2.1 (snap), login via CAS stopped working, the login window appears and after successful login, the CAS login window closes but does not redirect us to Rocket Chat itself, clicking on the CAS login options again does nothing because I am already properly authenticated in CAS. In version 6.1.15 everything works fine - does anyone have a similar problem or have an idea why it stopped working? There is no information in the syslog itself that would help to solve the problem

We are facing the same issue, but only with the web version. The problem does not occur on the macOS or Windows client.
Currently, we are using version 6.2.5 and running it in Docker. The logs appear fine on the RocketChat server and the CAS server, but we are unable to proceed past the login page even after successfully logging in.

If you have found a solution to this problem, could you please let us know?
