Hi @danield, welcome to the GitLab Community forum!
@dnsmichi is on the right track. Can you check if you can get the license info via the API?
GET <external_url>/api/v4/license
After upgrading, did you restart gitlab with gitlab-ctl restart?
If not, can you restart gitlab and let us know if the problem persists?
For insight into what is causing this error, I suggest using gitlab-ctl tail to tail the logs while reproducing the error.
Where to look for details on errors getting the license in the web UI:
- /var/log/gitlab/gitlab-rails/production.log
- /var/log/gitlab/nginx/gitlab_access.log
