Home Assistant iOS App - Failed to connect

Hi!
After reloading HA from backup into my Raspberry Pi 3B I tried to reconnect to the server by iOS mobile official application with my iPhone 11 but it doesn’t work again as in past.
I have attached the screenshot of the error.

I hope someone can help me. Thanks in advance!

Hi,
same problem, connects via VPN to an iPad mini2 using HA app iOS. I have the IP registered in the VPN network and HA OS running and accesses it from the mobile with the same method and works, What can happen? ipad, ios app, VPN?

Solved using another device.
