Update fails - docker

Ubuntu server - Docker - HA

I have done 3-5 updates, by just pressing the update button and it worked just fine. Now I get errors.


Now getError: Unknown Error, see logs!

What is going on?
for some reason I have 2 Docker images

but container is created based on 1

Case closed.
After restarting the server and checking all containers, it finally worked. Something was blocking pulling Docker images.
