Hi all,
my multiplayer isn’t working anymore. It is not loading ANYTHING. My profile doesn’t get loaded and multiplayer screens don’t get loaded.
It worked completely fine 24 h ago and I’ve been trying to fix it for almost 2 hours now… 
What I tried already:
-Wait 30min.
-clean cache of all blizzard games
-reinstall all blizzard games & battle.net
-used the sc2 repair function
-changed ip4 & ip6 DNS servers to 8888 and 8844
-dns flushing / checked connection / ipconfig renew
-made sure every firewall / 3rd party software is deactivated
-made sure all the ports (6112-6119) are forwarded / open
-cry a lot.
Singleplayer is working just fine…
EDIT: Whenever I try to open a Replay I get a blackscreen.
Hey neph,
Thanks for providing a detailed list of the steps you tried already! Definitely sounds like a weird one! Could you please include your system files in a reply so we can try to help have a look? Also, is it just a regular home broadband connection you’re on yes? As opposed to like a university campus or other such shared connection?
