Terramaster Tailscale incompatibility and Plex woes
I got tailscale and Plex all setup, bought a new router just to to run tailscale at my remote location, everything was sweet... for a week... then it inexplicably stopped working. Everything seemed fine... the NAS was accessible remotely, I could ping it, access it's admin interface. I could even access Plex on my computer and play movies. But on my TV and phones, nope. It was like my NAS was completely invisible... even to Remote access viewing, let along "local" viewing. I was tearing my hair out, eventually by chance looked though my NAS settings and found Remote Access "On" with a 100.x ip address that looked like a tailscale range, but wasn't its correct tailscale IP. So apparently this is Terramaster's remote access solution, and it takes an IP address range that tailscale thinks it owns, and this can lead to inconsistent behavior. So I disabled that, you don't need it I guess if you are using Tailscale. And hallelujah, everything started working again. So I post this for others to find... if you're using tailscale on your Terramaster, turn off Remote Access.
