Can't access HA from different WiFi but works over cellular or local connection



I can connect to Home Assistant over cellular or on the local WiFi where the rpi 4 is located. I can’t connect to it from my parents WiFi. Se printscreenens. My patents WiFi is good and the speed is also good. What can be the problem.?

I’m using cloudflare to remotely connect to my HA. I think it has worked before but now it doesn’t…

Tried to connect to my brothers HA through my parents WiFi but same problem here. He also have the same setup as me but in a different place.

Any ideas?
