I have a server address with both 443 and 80 ports open. I can connect to 80 just fine but 443 is being cut. I want to know where, at which point on the route, it is being dropped.

How can I get this trace?

    There's no reliable way. Once upon a time, ICMP "Destination Unreachable" messages were designed to give you this information, but giving users (potential hackers) information about which firewall is dropping their packets is considered a leak of security information, so many routers and firewalls are configured to not send those messages, and many even filter out ICMP messages all together. So you could try watching for ICMP Destination Unreachable messages and maybe you'll get lucky, but probably not.

  • Yeah, problem is that only port 443 dropped, ping works just fine

  • If ping is working, mtr as in "My Traceroute" might be of help; available for Linux:en, not sure how it is with Windows. Check the man page and note options u,T, S and P. Note though: port 443 is mostly used for secure web browsing ("https:" URLs); are you sure the server does this correctly?

    Just to be clear, ICMP is used for much more than just ping. Ping is just ICMP "Echo" packets. I was talking about a different kind of ICMP messages: "Destination Unreachable".

  • I'm not sure how that would help. @Hannu I can connect to port 80, but not 443, but proxy works fine with both.
