Plex iOS app with Tailscale

Hello, I have a problem with the Plex application on iPhone that does not connect to my Plex server with Tailscale.
I get a 401 error when connecting manually (authentication ?)
I tried to authorize the network of Tailscale in 100.0.0.0/8 but unfortunately it does not work. No problem on Chrome but the interface is much less adapted to a mobile device.
My question is : which network is to be authorized without authentication on the Plex server to use it with Tailscale ?

Thanks in advance
Jérémy

PS: I use Tailscale because my internet connection is in 4G at home so I can’t redirect to the internet.

I’m facing the same issue. Did you ever manage to resolve it?

Edit: I have just found the solution on Reddit:

I got it working similarly. I did not have to enable https or Magic DNS.

For my situation I was trying to use plexamp.

In Plex, I have remote access set to: “Not available outside your network”

Then under Settings>network

there is a “Custon server access URLs” field

I put my tailscale ip address for my plex server there. “https://:32400”

Example: “https://your-ip–:32400”

After that I could connect using plexamp to listen to my music from my phone. Whether on wifi or cell

Here is what the manual says about this field:

Custom server access URLs

A comma-separated list of URLs (either HTTP or HTTPS), which will be published to plex .tv for server discovery. This can be very useful in a few cases: if you’re using a VPN to get back home, if you’re using a reverse proxy in front of the media server, or if your networking configuration is otherwise unique. For instance, if you have your own custom domain with subdomain, you might add:

https://plex.–mycustomdomain.com:32400

Hope this helps someboby.

similar to what aakoss said, but spelled out exactly what I did.

I’ve finally found how to do it!
