I thought it was just bad timing on my part. I also tried disabling autoupdate and didn't have much success. I did remove all traces of my CP install (image, container, config, etc) and reinstalled your docker image. I run in the same problems I had when I disabled autoupdating. Unable to login, able to login but when adopting my server things stop working, endless reconnection loops. Generally just a nightmare.
I'll just wait for you to update the docker image with the new crashplan. I imagine you're getting tired of it as well. 90% of the time the UI is unnecessary, I just decided to dive back in at the wrong time.
