Funny server problems since yesterday...

I have not made any changes on to my box and these problems have started all of a sudden:

The caching nameserver is not working anymore, it is not resolving anyting else from the server.

E-mail has problems, all mailboxes return a “autorization failed” error. seems to have disappeared. When I try accessing the wemail interface I get:

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /webmail.

Reason: Error reading from remote server

Apache/2.0.54 (Unix) Server at Port 80

When I log in to nodeworx/siteworx, everything seems okay… also, all the hosted websites pull up fine.

Maybe someone can help me resolve this?

houndbee, I think you have a ticket open about this issue and Paul is checking it out.
