I keep getting a critical error lost connection to Ubisoft. My orders are broken as in they are unavailable and there is no way to pick new orders. I can't connect to matchmaking as it's saying I'm not party leader even though I'm queuing solo. There was only supposed to be maintenance on the Xbox so why is it that for honor is unplayable. I'd even just play custom games if it wouldn't kick me after 2 minutes.
Today's maintenance is just on Xbox One, and hasn't started yet.
Can you go through the steps found here, especially the part about port forwarding.
If you're still having the same problem after this, can you please let us know.
