Keep getting this message whenever I'm trying to use Windows\Android app to connect to the server. I just installed the server so wasn't able to use any apps initially. The Website version - works perfectly Used the "Latest" server from the website, then the Beta version (Version 4.8.0.39 beta). The same issue. Then I thought maybe the problem with the client side. Tried older versions of Android apps, the newest, from google play, directly APK from the website = the same issue At
