curl_easy_perform: Dedicated Server Error

[LOLWUT]

I am using a program called SRB2 DiscordBot to host a netgame server.
But however, when the console tries to register to the master server, all i get is a curl_easy_peform error, even though the master server link i used is by default. While my server was still running, the server browser said that my server was unreachable, but when I open SRB2 during this process, my server still shows on the server browser in-game despite the error.

Is there a way to fix this?

by the looks of it, it seems like it's failing to resolve the ipv6 address, since the first time, it seems to succeed. try starting the server with -noipv6 and see if the error goes away.

the reason why it's doing this is because it tries to register both it's ipv4 and ipv6 address so both ip versions are available when applicable, but sometimes, it fails to figure out that it doesn't have a valid ipv6 address it can use, and therefore tries despite ipv6 not being available. i have a feeling this is the case here.
