Hello experts.

I cannot connect to my server using (502 Bad Gateway error)

but I can connect using

I can't connect to anything on the server at all


The zone file on my ISP/registrar's server seems to be fine and when I ping it seems to pick up the IP.

I'm guessing it has something to do with firewall or IIS settings on my server. Please help!

    Hi Clever Bob,

    I will need more info on this-  IIS logs which will show connection errors
    Windows event logs on IIS server
    and try WC3 Extended logging
    Also, protocol analyzer such as wireshark to analyze http requests
    Is there a proxy or ISA server upstream in this network?
    Have your changed the IP address on the IIS virtual directories
    or made any changes and not restarted IIS?
    As a test, you could try opening port 53 (DNS) outbound in your firewall to allow DNS requests through
