[vgskye]

please confirm that https://broker.e4mc.link/getBestRelay is reachable from browser. if not, it's an ISP problem I cannot fix.

[lucananni93]

Yes it is reachable!

[vgskye]

that is strange. please confirm above URL is reachable via secure connection and your internet connection does not have any root CA based HTTPS monitoring?

I have the same problem, I don't understand how to solve it, my friend is fine, but when I try to log in or create a LAN, I get an error, can you tell me how to solve this problem?I didn't really understand what you meant above.
