Spaghetti Detective config wizard never starts

I'm trying to install the Access Anywhere - The Spaghetti Detective (1.2.5) plug-in.

All is well until I re-start Octoprint and the configuration wizard never starts. Any ideas? Maybe a manual configuration is possible?

Is there a file where Spaghetti Detective writes errors?

Yes the webcam is working and I have access from all local computers. The plugin is listed as installed and enabled. If it matters my Octoprint server runs on an Intel "core dual" desktop PC running Debian 9.

Yes I know there is a discord server for this plugin but I'd rather find a different remote access method then have to deal with Discord.
