What happens if you try to access http://10.0.0.130/ from your dektop computer inside the LAN
Type it exactly like that with a / (slash) at the end. If you can access it , check if your proxy has access to your printer’s IP maybe a firewall or something is in the way.

I want to use apache as a reverse proxy for an internel IIS site. I was unable to Setup Reverse proxy, so, for testing purposes, my internal site is a network printer web page. My Setup: Internet -> Internet Ip address ------------------------> printer web server (dns website) (dns website-for-internal) My apache webserver is configured with 2 virtual hosts, one for the site itself, the other for the internal website. When accessing website-for-internal, the apache logs show “proxy: Error Reading from remote server returned by/” Httpd.conf <VirtualHost my.internet.ip:80> ServerName website DocumentRoot /var/www/html/ DirectoryIndex index.php </VirtualHost> <VirtualHost my.internet.ip:80> ServerName website-for-internal ProxyRequests Off ProxyPreserveHost on ProxyPass / http://10.0.0.130/ ProxyPassReverse / http://10.0.0.130/ </VirtualHost> At this point I’ve even tried to Setup the reverse proxy without using a virtual host but I get the same result. Also with different settings with the Proxy configuration (retry=0, Keepalive=on, connectiontimeout=5, timeout=30, etc,etc) wireshark shows incoming and outgoing traffic for the internal Ip adress. Browser error: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET <http://teste.di.ubi.pt/> /. Reason: Error reading from remote server Any ideas please?
