I deleted all VPN applications, but I can't find the reason.
Perhaps, as Apple writes, the kernel has been changed, but I don’t know how to check this.
Can Apple test my system remotely to determine the cause of the relay failure?
iCloud Private Relay is not a VPN. It only works in Safari and certain apps.
I have never used Private relay... or a VPN.
For what Apple can do and not do for you you in your region:

You can try making some changes—
issues with “Private Relay Unavailable” it could also be your network settings ...
... 'limit IP tracking in mail and safari' will kill private relay if turned off. Turn it on, then reboot.
