I just got a mod. When I started it up and connected to the Mod with a browser the browser-UI wanted to install 1.0.6. This seems to have worked, though I could not figure out how to determine what version of the firmware is installed on the Mod itself or on the web-UI. Well. the URL on the web-UI somehow became "http://192.168.51.1/?v=1.0.6" so I guess that means 1.0.6 is installed.
Ok, in the web-UI I tried to update some plugins but got the "Could not install plugin: Unauthorized" error. I tried the above suggestion "Open this url => https://api.moddevices.com/v2/lv2/stats" but it did not solve the problem. I've tried different browsers (Chrome, Chromium, Firefox), different OSes (kxstudio, AVL2016), cycling Mod power, did not help. Any other suggestions?
