I'm stumped here. Getting a TCP RST from port 443. Spent too long on this one already. Any suggested ideas or any tools to examine more closely? I suspect IP white listing on the firewall/host so my IP queries are being bumped. Already did a tcpdump, and in process of enumerating domain names and reverse lookup to see if I need to type in a URL. I'm probably overthinking it. I know there are people here who know this shit.
