Server wont appear after latest update

Hi, during the past weeks i have been running my own server for a small group of people. However after the latest update which took place 28/02 2017 and 03/01 2017, my server no longer appears in the server list. Direct connect doesnt work for anyone either. I can join the server with “0 ping”, beacause well its local, but none else can. I have tried updating server but no good, any suggestions?

This isn’t related to ‘the update’ - probably a firewall?

allready tried disabling firewall & antivirus programs. :frowning:

Looking closer at the server, its no sending nor reciving anything. as in kbs/s is 0

I have the same problem In my VPS!
