Experiencing the same problem. Have tried reinstalling the game. Resetting my account password. Rebooting my modem, and updating it's firmware. Flushing the DNS and resetting the winsock. Restarting the computer multiple times.

Still can't log on to my main account on any of my computers using the standalone PC client, the Steam Client, or the iOS version on my iPhone. Interesting enough, creating an alternate account lets me log in and play on all platforms, so it doesn't appear to be a networking issue - at least on my end. I think.

Fingers crossed the update that comes for SOS fixes the issue, if not something sooner. I need my hit of MTG.

Ihave same issue with my Pc and android phone :-(

Ive been trying to login since the update and it doesn't let me. Ive been waiting to see if its a server issue. Also ive tried redownloading and still nothing.

Same issue here for four days now. Contacted support and have been told to change my password... To no one's surprised, it didn't change anything. Also tried the flush DNS fix and obviously to reinstall the game. Still unable to play on my account, but playing on a freshie works perfectly fine.

Same here!

is there anything we can do about it?

It's not even in the known bug section, i feel like they don't care

They better compensate us for this. This is absurd.

Same issue since the last update. PC oder phone, doesn't matter. Completely locked out.

Same issue since the update, app is totally unusable even after multiple re-installs. Playing on Android, Galaxy S23. Please fix this Wizards 😭

Same issue across multiple devices and after reinstalls, have been completely locked out of Arena since the update

same issue here

Having the same issue, returning player that had no idea there was a patch and had logged in on mobile during the update similar to previous comment. A different account works on my devices but this account gets the error on three different devices.

Also not able to log in after the update. However, as I‘m playing on the iPad, I realized that I left the application active during the update. Might this be the reason for the bug?

Day 2 of being completely locked out of my account (could have been happening for more time, but I only tried to log in like 2 days ago. Please fix this wizards or I'm taking my time and money elsewhere.

Ive been unable to login for a few days. I made a ticket but whoever responded clearly did not read. I have attached a screenshot of the error. The issue persists on mac, steam, and iOS.

Been 3 days still haven’t been able to play, spoke to support they told me to reset my password (which I did but is not the problem)what a joke this game is. Can’t correct a error they made for days then have the audacity to ask if I reset my password.

If this bug is account wide, then it's a critical faillure on the dev/publisher side, who would want to pay for anything if we are not sure we will be able to play because of this kind of bug

Having the same issue. Can't log in on mobile or pc. Happened after the new update.

Tried reinstalling apps on both platforms. Nothing.

Multiple reinstalls and cache clears still nothing working. Samsung s26.
