Hello again.
Thanks for your support so far

I've managed to figure out why everything stopped working (but have not fixed filebot yet) - QTS blocks all apps without a valid signature. I was able to start them from there new ssh console and now traefik is working again.
For that reason I'm now trying to fix filebot too.
I've removed everything filebot related (filebot, filebot node, Node.js, java - interestingly two java installers wer available in the console, I've removed both)
Now I'm currently trying to install java from your repo but it seems to be stuck at 80% for the past 20 minutes. The github entry says that it might take long to download the package, but should it take that long? I'm at a 150 Mbps line.
-edit-
Just checked the log and the folder where the log is stored. It's still downloading the package

Will update you once this has finished.
