Keep getting disconnected at the end of missions when soloing

[Wizzy]

I don't always have folk to play with, so I just chill in challenging missions, however, it completely takes away my will to play the game, when for 2 days in a row now, I have to repeat the same mission 2 times, so I can the 2nd time around actually complete it. The game disconnects right after I'm done clearing out the map and about to call extraction.

And unlike games in a squad, I can't just rejoin, nooo...I lose the 30+ minutes for absolutely nothing, and still have to repeat the exact same mission and hope it doesn't disconnect again. Can't really bring myself to play anymore unless with a premade, cause what's the point? It's a waste of time. Go through the mission just to disconnect? Yay...
