Failed to connect to match making server

[xrevxoltx]

Has anyone else experienced this or know what the problem is?

I haven't had my server running for a few days, but I just put it back up and this is the error I'm getting.

deactivate your firewalls (router and pc) and try again.
if it works, check, which of them is blocking you.
maybe you had some update in the last days?

your official (public) IP is fixed?
is it still the same as some days ago?

your server is also still running under the same internal IP as some days ago?

is your portforwarding still active and pointing to the right internal IP adress?
TCP and UDP activated?
