HTTP ERROR 400 - Problem accessing /service/preauth

Post by adnese »

Hello,
one mailbox cannot be used; after trying to login with valid creds 'wrong username or password' message is shown. Logging to the mailbox from the admin interface brings:


HTTP ERROR 400
Problem accessing /service/preauth. Reason:
hmac failure
Powered by Jetty://
Tried to change the user status without effect.
Thanks for any hint.
Regards,
Adrian

Please check the data/time on your servers. If they are off by more than 5 minutes preauth will fail.
