Webserver protection fails with 'error reading status line from remote server' in reverseproxy log

Gerard Timmerman

Hello,

After changing from a virtual UTM9 to a XG115 appliance, the webservers are unreachable from the internet when we use web server protection. Only https forwarding is working while we search a solution. We have two Windows IIS servers behind one WAN-IPaddress, two different certificates and two different URLs, both servers have the same problem after the change from UTM to XG.

SSH reverseproxylog shows 'error reading status line from remote server'

Browser shows: The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /SynergyMobile. Reason: Error reading from remote server   The same applies to /owa or whatever we try to open.

We applied a new protection policy with minimal settings, nothing we tried makes a difference.

Any ideas?

Kind regards, Gerard Timmerman

    Sticky Session Cooky did not make any difference, I also removed the path specific routing to no effect.

     

    When I google on the response: Proxy Error,    The proxy server received an invalid response from an upstream server.
    The proxy server could not handle the request GET /.  Reason: Error reading from remote server,    I find lots of references to Apache problems in combination with SSL on webservers.

    The strange thing is that both the Synergy server and the Exchange server have this problem, and both worked when we still had the UTM9 in front.

    Best regards, Gerard
