3. An android phone uses data to connect to the internet.

4. Unity side run the WebBrowserInput sample, the Phone side opens Chrome searches the public IP address of the GCP, and open the videoPlayer sample. The video window is black
   

5. when the phone switch to wifi connecting to the same local network as the PC, then the video is successfully streamed.
   

Current Behavior

When connecting the phone to data or other wifi (not the same local network as the Unity), the phone browser cannot see the video

When connecting the phone to the same network environment as the Unity, then the video streaming is successfully received from the phone browser.

Expected Behavior

Anything else?

GCP log when the video stream failed.

I also encountered the same problem, but in the end, I tested that there was an issue with "videoplayer", but "mulitplay" can still be opened. You can try it, but there is a 30 second disconnection issue
