Even in I set a custom server jar, it says it fails to resolve. Possibly something with docker?

@limber viper It's a DNS issue.

limber viper
# frosty marsh <@103306913780879360> It's a DNS issue.

I'm a bit of a noob so I'm not 100% sure what I should do here. I did the command resolvectl status and it reads ```root@ubuntu ~ # resolvectl status

172.18.0.1

limber viper
#

When I change the dns to the one that shows in resolvectl status, it gets hung at "downloading mojang_1.21.5.jar"

#

and if I set it to cloudflare I get java.net.UnknownHostException

cobalt aspen
#

thats one step forward atleast

just a wild guess. Try removing the ipv6 since its optional and maybe it hangs on it.
