Question My friends can't get on my server because "connection timed out"

[MacheteT]

I have poured countless hours into making my server function but no one can connect to it. i passed the server port through the firewall, port forwarded the port to my router, made sure my VPN was off and it STILL DOESN'T WORK. the thing is that i changed to a new router around a month ago, which might be the source of the problem but i don't know how to fix it. the server version's 1.20.2 if that helps
