hi, my friend is having trouble connecting to my (zombie, fabric, whitelisted, 1.21.11) server while i can, it says 'unknown host' for them, while my connection to the server seems to be acting fine, and the server itself IS in fact running correctly. on the console it said this multiple time :
"Disconnecting [NAME] (/1872727272idknumbersnumbers): Authentication servers are down. Please try again later. Sorry!" '' [User Authenticator #4/ERROR]: Couldn't verify username because servers are unavailable" (also timing out and disconnecting because it took too long to connect)
i dont know if it is their problem because of DNS/ internet issues (their wifi is fine, they do not lag at all), because when they told me their trouble i had the same thing going on but i changed wifi and it worked. also tried if it was the ip, if the client had a problem, but everything mirrored my own data and it still had this problem. they tried everything I did but nothing worked either. is it a server issue or am i missing something? thank you for taking this into consideration.
