One client can't connect.

[Seikoh 1]

So my server has been up and running for a few years now. I have never had any issues connecting to it either remotely or on the local network. Currently my phone, my Chromebook, my computer and all three TVs in the house connect fine. Obviously those are LAN. My phone connects remotely as does my sister's TV who lives on the other side of town. 

The only device that won't connect is my girlfriend's Google pixel 8. My phone is a pixel 9. I've tried the entire troubleshooting guide as well as connecting hers through the Emby connect email, inputting the IP and port in the app, and going directly to the IP address/port in the Chrome browser. The only way she can connect is when she's on Wi-Fi at home. 

Does anyone have any ideas why this specific device would be the only thing that can't connect to the server remotely?

Is she using an VPN service when on Cell network.

Or some adblocker.

No. We're both on Google Fi also. The only difference is she is using a virtual sim.

 

Sorry being late in replying I do appreciate any help
