Same error, first login today, clearly server issues....

Cannot reconnect, game bugged in some variety since update.

Same issue just put money on the game last night and now i can't play

Getting "lost connection" first, clicking reconnect, then get "authentication" error. What is going on lately with MTG Arena? So many log-in, in-game, and processing errors on top of the constant algorithm issues.

Impossible to Connect me

got this message in the middle of a game...

just when I thought I was about to play some Magic this happens SMH

I am experiencing this issue on both my laptop and my mobile device.

So, this error is back....

I got kicked out of my draft, and now I am not allowed back into the game.

same

Same problem... logging in from Italy if that makes any difference

still not able to logging in, the best game ever, zero bugs.Awalys when they release an update i have some kind of problem.

After logging in the program doesn't load the initial scene page. Tried a hundred times but same result. Just a black page.

Crimson vow update has effectively blocked me from logging in. On PC.

Having the same problem after Crimson update.

With the Crimson Vow update... unable to login due to Authentication Timeout

I have the same issue and wizards support said that it is no one problem reported, that I have to uninstall the game and install again. I did it but the problem it's the same.

Mot able to log in even after attempting and restarting and redownloading

just got this bug, can't login now :/

Cannot login, please get this fixed
