Today one of my customer told me that he was unable to use his webmail.
Checking the url domain-name.com/webmail I got the following:
[h=1]Proxy Error[/h] 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
[HR][/HR] Apache/2.2.31 (Unix) Server at www.domain-name.pt Port 80
I havent change anything on this server for a while, so I don’t know what really happened here. Maybe some update?
