Execute sudo -u postgres temboard-agent -c /etc/temboard-agent/15/pg5432/temboard-agent.conf discover to refresh discover data as a workaround.

Please keep this issue open, temBoard should handle gently this situation.

Note that we recommend using temboard register-instance on UI side rather than registering on agent side. This avoids asking for admin credentials on UI and prevent agent to UI request initiation.

my pg_hba.conf file was not configured to go out.
I modified and restarted, i added on UI, it's ok now
Thank you bersace
