Hello Titanas, welcome to the community!
Oh, this seems quite unusual, but let’s see what we can do about it.
What operative system and browser are you using?
When you used Fing it should have given you a local IP address (like, for example, 192.168.1.47 or 10.10.something.something). Have you tried to connect to that address directly (by writing it in the browser address bar and pressing enter) instead of rs.local?
If you are able to connect via this way, can you then click on Download Log Files and post them here for us to check? Thank you.
