When I change server IP to intranet IP 10.0.0.0/24 there is a problem to log in to Horde:
Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /horde. Reason: Error reading from remote server
It takes a long time and usuall ends with an error that the site doesn’t response. Any idea what to check?
Thanks in advance.
