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!

This is so frustrating, fix your **** guys. People pay money for this game, losing due to a lost connection is infuriating. How long will this be a persistent issue for so many players until you FIX IT!

I am unable to maintain network connection since the last update. I lose connection to server when deckbuilding and when playing. Sometimes it happens when I just change to the "Store" screen or "Decks" screen. I have uninstalled and reinstalled arena multiple times.

I've had the same problem, even happ when I was deck building... extremely frustrating! I've lost several drafts too

Network error on turn 2 of a draft. No option to even attempt to reconnect, just a free win for my opponent and an undeserved loss for me.

this is getting EXTREMELY frustrating WoTC. I have now lost no less than 6 matches on ranked ladder and 4 matches in ranked limited. Fix the issue. It isn't with my PC. It is an issue on the server side.

During a ranked match bo3, when sideboarding

Same problem happened several times - never took the care/time to report it, but after a while it just gets too much...
So, drafting IKO in Quick Drafts (never had any problem during the drafting process)
1st match, opponent is found, and we both land in the game
Just after getting in the game message "Network Error" appears
Priority is left to my opponent (timer on their side) - and after it gets to 0, game is just left impossible to interact with
When reconnecting, I always get the game loss
Starts to be a pain in the a**
