I've been troubleshooting it for the last few days and I can't seem to determine the root cause. I've already reformatted the system, verified that the ports are opened, applied firewall rules for the app, tried a different network card, messed around with router settings, and I'm able to RCON in via the static IP address with several different tools (RCONTool, Atlas Server Manager, RCON for ARK, etc).
While other server managers work, they really don't compare to yours in my opinion. I was just wondering if maybe there was an option to change the IP that it's pointed to, similar to that of other managers. If not, then I completely understand - it's probably something hardware related on my end but I just wanted to be sure that I wasn't missing something in the config.
Thanks for all of your hard work and the swift replies.
