Sorry - hadn't seen the other issue when I put this here. If you have verified your internet connection is not the issue, the best place to track this is over at https://feedback.bistudio.com/T175914 (for PC) or https://feedback.bistudio.com/T175909 (for XBox) . While those issues are related to experimental, there are recommendations you may wish to use for the released launcher as well - also some people have listed more of the related directories I alluded to in my previous post.

It may be important to note that I run on the game (normally, quite well) under Linux.

I ran into this issue and wanted to share my experience finally resolving it yesterday.
