Nostr Relay Not Working

Hi, I have installed Nostr relay and followed the instructions as far as they go with a couple of different clients, Astral and Iris. The relay is installed and says running and I have applied the relay URL to each of them. I’m not running a VPN and not using tailscale. All of my other Umbrel apps connect up perfectly on my home network. Can anyone help please?

Really impressed, thank you. That fixed the problem, it was a security issue on Chrome.
