App not starting after update

Sorry if I am asking silly questions, but I am rather new to TrueNAS.
Recently I triggered an update for the Nginx Proxy Manager and it did not start up anymore since then. I am getting an error in the logs:

Failed ‘up’ action for ‘nginx-proxy-manager’ app: npm Pulling
npm Error Head “https://registry-1.docker.io/v2/jc21/nginx-proxy-manager/manifests/2.13.2”: unauthorized: incorrect username or password
Error response from daemon: Head “https://registry-1.docker.io/v2/jc21/nginx-proxy-manager/manifests/2.13.2”: unauthorized: incorrect username or password

somebody got a hint how to get this starting up again?

ok, solved the problem, but I have to admit it was my own mistake:

I added a registry to Docker-Hub before, but deactivate the account in Docker-Hub later without removing the registry also in TrueNAS. I guess the system was looking for updates on Docker-Hub, but due to the disabled account couldn’t access anymore.
