I had the same problem a while back, and it was my ping. Check your ping and make sure you don't have a lot of no-replies (I used bbc.co.uk as recommended on FDev Support pages).
I had a lot of no-replies on my 2.4GHz network and got the adjudication server disconnects frequently. I changed to the 5GHz network, which showed no ping issues and haven't seen the adjudication issue since.
So, this particular error seems to be directly linked to answer-reply speed between us and the server. Since several people are seeing it since the update, it may be caused by server load atm, and may clear when people "calm down"
PS: Sorry for the OT
