Cannot join multiplayer campaign due to unspecified error

Me and my friend both cannot join each other multiplayer campaign since yesterday, when we join each other campaign, its state that it has unspecified error, sorry for poor English.

I am also having this issue, I have followed the trouble shooting guide but this doesn't seem to have done anything.

Having this same issue with a friend, does anyone know if there is a way to fix this yet? We play multiplayer campaigns all the time and as recently as last week and it has always worked fine in the past.
