An unexpected disconnection occurred

I've already lost countless maps to random DCs back to the login screen.
I wouldn't mind it if the map does not close. It's impossible to sustain maps like this. I tried many different EU servers with no luck.

I want to play, but this is completely ruining everything for me.

It's getting worse. Can't even finish a single map. What is happening?

The same story :( 2 times per hour Unexpected disconnect
