I've been working for 1.5 hours and have yet to receive the warning "Warning: Server port is not accessible from the internet." Here's a rundown of what I've tried:
I used TCP and the port 1234 to enable port forwarding on my router.
I used TCP and the port 1234 to enable port forwarding on my Xfinity modem.
TCP port 1234 has a rule on my firewall.
Both the router and the modem were restarted.
I updated the firmware on my router and re-enabled port forwarding with the same settings as before.
Is there something I'm overlooking? I'm at a loss for words.
