This looks like a network related error. Do you followed the docker installation instructions (network mode host, iptables rules)?

Can confirm ftp upload is not working. Tried with 0.1.7 and 0.1.8b

With 0.1.8b there is a uploaded file. The sha256 match with the file in bambuddy archive.

To my memory it worked with version 0.1.6.2, I'll try with it next.

I was running 0.1.7 in docker in host mode. I'm testing 0.1.8b with a manual install. It's on the same network and I don't have any routing rules that would block anything. Sending files from Bambu Studio on the same computer works.

I don't see a docker tag for 0.1.6-final, but I did test some others for reprinting...
0.1.6b11 - works
0.1.6.1 (reports as 0.1.7b in app) - failed
0.1.6.2 - failed
0.1.7 - failed
0.1.8b - failed but with timeout
