First 2 hours of playing the game and encountering an unrecoverable crash while playing vs AI. This is promising.

As CheatyMagee described, I have full control of the battlefield, but the spell cast won't resolve. The turn timer started, but 'ran out' and the hourglass animation is just sitting there. My opponent had been having some connection issues all game if that helps.

Same thing keeps happening

I am having the same constant network errors

Same issue. Network error at beginning of game. could not resume game. Counted as a loss.

Same thing happened to me a few times over the last few days.

I seem to be having an error reaching the network server, after the most recent update. I can't even log in. Can't even create new bug logs. Kind of like the server is rejecting my computer.

Game is completely frozen.
No network reboot.
No timeouts.
Still have full function on the battlefield but nothing resolves.

Have not been able to start a game without the "Network Error" message in a number of days. I've reinstalled, I've rebooted, I've tried everything I could think of. I can no longer play a game of magic.

The problem started with the last download, probably when I ran MTGA on Sat. June 27th.

What is the solution?

Same problem here. It keeps saying network error and then the connection is lost. Nothing I've tried works so guess is their servers problem.

Please fix it

I'm getting this error both on Epic Games download (OSX) as well as through GeFore Now... Any game I try to start has this error.

Keep getting the network error as well not sure what's going on I have kids wanting to play and learn and get ready for tournament but can't because it does not work.

o arena travou e perdi uma partida importante
me fazendo perder ouro e gemas

Wizards, please fix your servers!!! Every single game I’ve played this week so far has hat a network error and the only option I had was to exit the game!!

had the same problem today
although i was able to relog in time the game state wasn't saved correctly
the mountain I've played t1 was gone
when i tried to use it later in the game it was discarded :-)
I've added screenshot and log

Same issue, got disconected twice when i was about to win

Just tried playing with VPN with outgoing point in New York, but the issue still occurs.

I've added some logs from my case, which seems to be similar (or the same), and the Wireshark network packets dump in the separate thread. Just linking it here, if that could be helpfull somehow:

The solution is: get EU servers. Connection to US is bad for everyone nonUS.

Holy **** WOTC FIX THIS **** ALREADY!
