Anti -Cheat authentication Error

I have the exact same problem. Worked fine 6hrs ago and suddenly I came back after 6hrs and this happens. I also re-installed the game and still have the same problem. My advice is that we both wait for someone to give us an answer

Yeah idk if its from the new gundam event or if its the new windows security update i just downloaded, idk. Let me know if you figure it out.

Got the same problem nothing seems to fix it.

Just tried again after 12 hrs seems like a server problem at this point. Were any of you guys able to join back in after having this problem?

No not yet

Hey man i found a solution. I think its a temporary solution but i was able to join back into the server and play. Download “cloudfare warp” vpn. Turn it on, and try launching the game (the vpn is free and safe so dont worry)
