Failed to connect instance

Was playing with my friend on Rustbowl, and we were doing some farming like usual. Until I saw my game lagging like crazy. It risen to 20,000 ms. And then I lost connection to the server. I tried logging back into that character but kept telling me Failed to connect instance. So I hope the problem fixes itself. The only time I get on to game with my friend and this occurs lol. And the server ping is 34 ms now. Maybe its just Rustbowl never had any problems with any other maps?
