Same here, can't connect. Updated the game, doesn't work. It happened before, might fix itself, we'll see.

can not log in whats going on

Having the same problem. Unable to log in, unable to connect to server. I was playing less than an hour ago. Server status is good

Intrestingly the status page shows no problems. I also got disconnected during the game and after that I got the same message.

Same here!!!

Same problem here. got kicked out of a draft ~40 minutes ago and couldn't log in since.

Logging in on mobile via WiFi. Got in an hour ago, can’t get in now. Updated the game a couple days ago.

Logging in on my mobile network, I also got Error Code 16 at the login screen. Can’t seem to replicate it though.

“Unable to authenticate” or “Connection lost” messages. Unable to access app

I have the same issue. I wonder whether the download has a bug that needs fixing now. We all seem to be caught in a loop that will not let us authenticate despite the system recognizing our ID?

Can't connect, yesterday it was working.

Same issue here. First login of the day: "Connection Lost" and after clicking re-connect it's "Unable to login - Authentication Error for *** - Disconnected while waiting for response". Tried on different devices (MacOS and iOS)

Impossible to enter the game after being kicked out during a game

Upon launching client (Windows) pic (Arena_1_112121) when clicking Reconnect "when allowed, takes a couple seconds for client to relinquish control to select button" pic (Arena_2_112121) is the result.

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
