I'm having the same issue. Please help me understand how you fixed it. Thanks!

Updated the OP with the current error details.

I just tried to log in on a fresh install...same exact error. I don't understand what changed. I used to be able to login no problem.

The login/auth all seems to happen succesfully...then that error pops up at the last second.

Still no luck with this. Hoping someone can help...

I get the below error when trying to log into the FAF Client. When i hit the login button, i get sent to the webpage to authorize, which I do. I get the green check mark that it was successful and then this error pops up. I have successfully logged into my account and played on this client install in the past. I'm not sure what changed. Please help!
