I don’t see this issue in your log. All the connection tests to your server appear to be fine.
Can you try the following then get me logs?
- force stop the app
- start app
- take screenshot showing your server unavailable (I assume you mean the hubs show as unavailable)
- switch to your friend (I assume you are switching by picking a library from your friend)
- switch back to your server
- new screenshot showing the server ow available
- grab logs
upload log and the screenshots
