Cloudflared Tunnel Blocked by Network

I have installed Cloudflared Tunnel on a Mac, as I have done many times before, however this time something on the network is blocking it. I am not a network specialist so I would like to give some information to someone who is. What can they look out for on the network to see if it’s being blocked so potentially they can unblock it?

As an update to this, the Cloudflare destination webpage is showing an Error 1033. When I check the 7844 ports through Terminal I have success - nc -vzt region1.v2.argotunnel.com 7844 and nc -vzt region2.v2.argotunnel.com 7844 - “Connection to region2.v2.argotunnel.com port 7844 [tcp/*] succeeded!”

I have reinstalled the tunnel but no luck.

Any other ideas?
