Why does Private Relay show as temporarily unavailable on iPad Pro?

I am on an iPad Pro 11”, 2nd generation , iPadOS 17.5.1, and have had Private Relay turned on for some time now, even on my iPhone 15.

Within the past day and a half, I keep receiving a notification that “Private Relay is temporarily unavailable. Your iPad will resume using Private Relay tomorrow”. I have also received the same message on my iPhone saying the Private Relay will resume in 40 min. This message does not come on all the time, and not on a regular basis.

I have turned both devices off and back on. Nothing changes.

In settings Private Relay is toggled on.

I was just wondering if anyone knows if there is a reason for this.
