What is the issue you’re encountering

I am hosting app on my server. From my local network it is accessible via: 192.168.1.107:5050 I have tunnel pointed to this ip address. When i go to ip address on my phone i get mobile version of the app served. Problem is, when i try to addess the app with tunnel I get desktop version served. I have used live logs of my tunnel connector and was able to find that user-agent header is set as: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36
