It could be an increase in traffic in your area or problems with your ISP at that time of night. Try running network tests before that time and then during the troubled time to see if there is any major difference in Upload/download, ping, jitter and packet loss.

I am experience something like this too, yesterday night i was having random disconnects, weasel, honeydew and anteater from what i remember. Logged today before going to work and it is still having errors, I run tests on my network and seems fine. I will try when i go back to change channels on the router, clear cache on the game, idk, i just can't play activities because I wont connect or if i connect, i got disconnected on the run.
