I spent a little bit of time and got Minion running happily on Linux now that ESO can run under wine again (with a tiny patch to make the ground not... invisible). All went well, and I side-stepped those null pointer issues that happen during game detection. However, I am currently unable to search the online database and it appears Minion isn't capable of downloading any data from the addons database. I have some screenshots attached, but it's unable to match any installed addons to the database, nor is it able to allow me to search for new ones to install. (It won't even populate the dropdowns with category information.) I am not running a proxy and should have no need of special settings.
You can see in the log that it's recognizing some addon information but is unable to match them to anything from esoui's database. I'm happily able to ping and access the cdn and api subdomains, as the log shows the app can as well. The program works happily on Windows on the same machine and network setup.
