can you help me identify this in the logs? A timeframe of when this happened?

[caitmuenster]

Sure! We started attempts at about 3:00pm CET and stopped our last attempt at about 3:50pm.

[richvdh]

thanks, investigating now!

Turns out it's being blocked because users with [email protected] email addresses are blocked on this server... is it possible for the user to use a different account with a different email address?

[Zitronella]

i coud add another account [email protected] to my primary account and now i can log in the chat.

I have a @zoho.com address and I'm also unable to login with either of the single sign on services. Please fix this.

[richvdh]

the list of blocked domains is mozilla's choice, not mine, I'm afraid.

[Smile4ever]

I will open an issue in Mozillas bug tracker then.
