local host ip works perfectly i have a papermc server and when i try to use assigned ip by layit ti shows a red cross on ping area and also shows getsockopt error
First make sure everything is configured correctly and playit and your server is running.
for getsockopt here are the things you can try
you can try disabling ipv6 on agent settings if you have broken ipv6
using ip4.<address> where address is the tunnel’s domain
check your plugins/mods/texture packs ensure they are properly set up and compatible
check your security make sure its not blocking ports or connections
change dns and flush dns cache
if you have premium you can try using the ip:port
if it’s not the above it might be your isp blocking/filtering the connection in that case you can try regional tunnel from premium
