User navigates to their Appsmanager UI and sees the following message/warning at top of UI:
The cause can be related to the users idle time or can be related to a network/transient issue that is causing the UI to not function correctly, thus throwing the warning.
1. Refresh token by clicking on the banner as described in the banner message/warning.
2. Try logging out and back into cf to establish fresh connection.
3. Try using a different web browser to see if issue is still present. (ie if using Google Chrome -> try MS Edge)
4. Re-deploy/upgrade TAS by running another Apply Changes from Opsmanager UI to eliminate possiblility of transient issue(s).
5. If the issue still persist after performing the above, please open a ticket with TANZU Support.
