Can't Claim Help

Server Version#:1.43.1.10611
So I am running PMS on a PVE lxc, I can not claim my server. I am on xfinity server using deco mech 6 for my router. I have tried removing the permission.xml , tried changing my dns to google,cloudflare still not allowing me to claim my server. I am soooo lost here. This is also my first time diving into netoworking and virtual machines. So please bare with me.

OMG . I am such a dope. I forgot I had tailscale running on my node. I uninstalled tailscale. restarted the node and now I was able to claim my server. WOW.
