Yeah, UK here and a couple of times I get errors about not being able to connect to the relay server in London + Amsterdam also with a public IP address from my ISP, but seem to have no issues even when it shows them unable to connect to the relay servers. The external Tailnet down at fam members house is FTTP but CG-NAT’ed, and why I love how TS works around it. Somehow.
But I have to ask. Have you setup the Tailnet with this fix for IP Forwarding on a subnet router (this helps me so much for tech support on said Tailnet…) and also UDP

I’m currently on my phone but I recall having to ensure the Mini PC w/Ubuntu / Pi4 with Raspbian down at their house had both the above when bringing Tailscale, up
.
The way I do it for a family member with Tailscale is them having a couple of boxes down there (n100 with their Jellyfin server, and a RPI4 with a TVHServer) with my Tailnet signed in, and those boxes running both a “subnet router” and an "exit node"that both me and said fam member can use.
This means she has permissions to use the exit node wherever like I do to my own local LAN, to connect to her LAN and access things locally since you can assign them via the ACL’s / device perms.
I know reading docs can suck sometimes but honest to god the ones that Tailscale put up are pretty awesome.

Along with all the YT videos about it I didn’t even have to go nagging on forums to get it to work, and that’s a general first for me.
