Hi, I've been a happy customer for a while.
Since last week I've had complaints from users - see the screenshot.

At first I couldnt replicate it myself - and now I cant seem to authenticate at all.
Consistently seeing the "Something went wrong when we tried to authenticate you, and we can’t offer a quick way out" error.
How can I debug this?

FYI all the redirect and login URL are correctly setup.
I've tested on multiple browsers - with and without clearing cookies etc.
Also note - I considered that this might be some hidden usage cap or something like that and I upgraded our account. But that hasnt had any effect so far.

I cant seem to login at all...
Help would be greatly appreciated 🙂
