Unable de connect / start Gitlab EE on Google Compute Engine
I deployed a gitlab EE instance omnibus on a Google Compute Engine instance following these steps: https://docs.gitlab.com/ee/install/google_cloud_platform/
Everything OK. I have updated my VM on ubuntu 18.04 and I restarted the instance, everything OK. But, when I've upgraded my VM to increase his capacity, a problem occured at system boot :

And, I am not unable to connect to the instance via SSH anymore (Error 4003 because back-end is not working, and then I got a timeout when I use SSH on port 22)...
I suppose that the Gitlab instance used Docker to work...
Do you hava any idea for this issue ?
Thank's a lot
