Ok, so if you are on a physical device, you would have to use the FQDN or IP address of your computer instead of localhost
and open up the port as I mentioned before. Also, the physical device would need to be on the same network as your computer.
For example, if your computer’s IP is 192.168.1.10
then http://192.168.1.10:8080
.
Another option would be to use https://ngrok.com or https://expose.dev.
