Unable to login to Camunda cockpit after upgrading to 7.21.0-ee

After I upgraded Camunda from 7.17.11-ee to 7.21.0-ee, I cannot login to Camunda cockpit
These are the requests and response codes that are made during login:

/camunda/api/engine/engine/ 200
/camunda/api/admin/auth/user/default/login/welcome 200
/camunda/api/engine/engine/ 200
/camunda/api/engine/engine/default/telemetry/configuration 200
/camunda/api/engine/engine/default/identity/password-policy 401
/camunda/api/engine/engine/default/group/count?member=admin 200
/camunda/api/engine/engine/default/group?maxResults=25&firstResult=0 200
/camunda/api/engine/engine/default/user/admin/profile 200
/camunda/assets/cockpit.svg?bust=7.21.0 200
/camunda/assets/tasklist.svg?bust=7.21.0 200
/camunda/assets/admin.svg?bust=7.21.0 200

With camunda 7.17.11-ee ‘/camunda/api/engine/engine/default/identity/password-policy’ was returning 404. Also after I enter the credentials I see the Camunda cockpit for less than a second and immediately after that I am redirected to the login screen again. There are no errors in the logs.

As you are using EE, I would suggest raising a support ticket.
This is a user discussion portal, not an official Camunda support channel.

Have you upgraded your DB to new version ?

Can you give me the link where I can log a support ticket ?

Unfortunately, I can’t as I’m not an EE customer nor a Camunda staff member
