Here's my cellphone using cellular
Channels DVR Server
I'm going through a double NAT with my personal router and my ISP Internet Gateway, so direct connect impossible unless I open a UDP port 41641 to the Internet.
If you ensure that port UDP/41641 is not blocked, and that outgoing UDP and TCP/443 is permitted, Tailscale will be able to reliably serve direct connections.
I'll work on this tomorrow, wife is nagging me to fire up the grill

You will probably see better speeds installing Tailscale onto the system (i.e. QNAP package) instead of the one embedded into the DVR.

That is true that is why I installed tailscale on Windows.
Verified even with double NAT that port forwarding UDP port 41641 to one of my NAS devices running Tailscale enables a direct connection to it instead of through a DERP relay.
And it appears that tailscale status no longer shows the connection type,
but tailscale ping <tailnet IPaddress> does.
I installed Tailscale on my QNAP NAS and signed in which added it to my list of devices in Tailscale. I already have external port 8089 forwarded in internal port 8089 that points to the IP address of my NAS, do I change that external port number to 41641, or create an new entry?
No, you also don’t need to forward 8089 when using Tailscale.

Thanks, I added the port forwarding and it plays back fine on my phone. Ran the speed test on the client, and I was getting between 50 & 100 Mbps down. Now I just need to change the IP ports on my Fire TV sticks and test them, but seeing it runs on my phone, I don't think it will be a problem on the sticks.
Thanks for everyone's help and guidance.
Are you sure a checkmark beside the relay is an indication that it is active? The description states that the checkmark is only an indication of the preferred relay.
The docs advise to use tailscale status to determine if a relay is in use, and I cannot find a way to running that command with the DVR integrated Tailscale.
tailscale ping does
Where are you running that command though if using the built in version? If I run it inside my Truenas jail it is not recognized.
I no longer use the Channels DVR integrated version.
I'm using the Tailscale Synology package on the server and the Tailscale iOS client on my iPhone.
Currently in Portugal to USA. Channels DVR with Tailscale. Slow, shows lag and buffer. Plex, shows play fine for the most part with an occasional 1/4 second pause.
Not sure why. Much prefer Channels when traveling.
How are you port forwarding? There's no option for it on the T-Mobile router. WiFi can be turned off with HINT Control I believe but there's no port forwarding.

I'm in Portugal currently as well, and using Channels DVR with Tailscale has been fantastic!
Since the DVR considers me to be streaming from "home", I do have to adjust the playback settings on my FireStick 4K Max (2nd gen) at times. I could probably leave it set to 3 or 4 Mbps all the time, but usually I can stream at "Original", and I prefer to use that 
-- and then adjust down when needed. On the Algarve now, but had similar results in Lisbon.
We're in Porto. The rain has been unforgiving. But love the country. Heading to Lisbon next. Running Tailscale on Synology. Wifi is not that good at AirBnB. Probably need to adjust something somewhere.

Totally worth it to get Tailscale dialed-in. I highly recommend having an "exit node" set up on your home LAN as well. Netflix, Prime Video and such all work like we're at home.
I'm using Tailscale on my Channels DVR host, not the DVR integration. I also it have installed directly everywhere where it can be, and use "subnet routing" for the rest. Magic DNS rocks too -- hostnames for everything.
Big surf warnings up your way for today?
Going to work on Tailscale when I get home. Surf is crazy. Even between Lisbon and Porto they're about 15'. Nazare is currently 25'
How is Sling tv able to remote stream my local channels.
