Tailscale + Hassio app

Hi everyone,
I installed the tailscale add-on, everything seems to be ok and I can connect to me HA using the browser in my phone,
The issue is that for some reason I didn’t succeed to use the hassio app to connect to HA.
I check several times the address but it just doesn’t work.
Is anyone can help here ?
Thanks

Android or iOS?

Android.
I think it somehow related to certification.
Since in the browser I first approves the certification and then continue to the site.
But seems that the app doesn’t allow to bypass the certification.

correct you must use a valid certificate with the app

What do you mean by that ?
That I cannot use the tailscale solution ?
