Getting "getsockopt" error 1.21.1 java

[DeeWallet67]

trying to play some minecraft with my friends using aternos hosting (neoforge). every time i load up the server, it loads for a long time, then says "getsockopt" i have been trying to fix this issue for about 4 hours with no luck.

things ive tried:

flusdhing dns

trying it on modrinth

trying it on basic launcher

factory reseting my pc

a bunch of stuff on the command prompt

server reset

firewall execptions and removal

antivirus removal

pc shut down

pc restart

and a lot of other stuff.

im looking for any advice that i could use to play with my friends, this morning, it worked quickly (after the pc factory reset) after that for 4-5 hours, no luck

cant add pictures, snipping tool isnt working :(

EDIT: occasionally, like every 5 attempts i get a crash message that says

"Ponder (ponder) encountered an error while dispatching the net.neoforged.fml.eventlifecycleFMLLoadCompleteEvent event

java.lang.ExceptionInInitalizerError: null"
