Friends can see server but get stuck at load

I followed 3 different guides to get my server up. All of them seem to work on my end and the server runs. My friends can see it, but when they try to join they get stuck at load.

Yes, I’ve port forwarded. No, firewall is not blocking it. I am running as admin. it is not passworded.

No, I can’t join it - but I can’t see ANY servers, which I have a separate post about. I’d think that my friends could join though.

Any solutions?
