Ios app cloudflare tunnel error 405

Hi guys,
today i’m having issues connecting to my ha instance with ios app, both my phone ans my gf one. Opening app result in 405 error. I’m using cloudflare tunnel. I’ve had this issue time ago, but i can’t rember how i solved it (maybe just gone by itself).
There are 2 weird things:
I can connect correctly via browser using my domain
Outside home i can’t connect nor in wifi or 5g, but if i’m home i can connect via wifi and via 5g (disabling wifi on the phone). I cant figure why.

The only thing i’ve changed yesterday is that i’ve logged out from my app and my gf one to change HA users on both phones. Can this be related?
