I think that error should only come up if a user gets deleted.

Can you give the exact scenario the problem occurs?
What do you mean by "connect" - register with Q2A system, or logging in?
Or logging in with an external login like Facebook?
If the error occurs with registration, is the user account actually registered and in the database?
What version of Q2A are you using?

Answer 1

I found the answer, the problem come from a security inside Q2A (number of IP/ number of registration by hour => as block me for a days. The actitivy of my Q2A is back fine to normal now.
