It works at home but not from my phone on mobile data

From home, your phone may reach a device on its local address without going out to the internet at all, so a test at home can work when outside access doesn't.

• Check the port is forwarded: Port forwarding explained.
• Run Can I reach it from outside? on My home.
• If it says "no answer", your provider may block incoming connections: see CGNAT.
• If your name only has an IPv6 address, the phone's network needs IPv6 too.
