its been like this for a while-the last time i could connect to the master server using the a dedicated server i hosted on demo server, then on the same day when i tried to set it up again, it said "cant connect to the master server"

nothing had changed, no settings updates or watsoever. clients could connect to me when i was able to host. now i cant? weird.

if need be any tests be made please state and i will perform them.

TY

Firewall? Has your IP changed? A little more detail please..

There's obviously something blocking the LFS server from contacting the master server. Check your Windows Firewall or any firewall running. And as mkinnov8 said.... more detail would be helpful.
