Critical domain WebSocket connectivity failures detected in your tenant

[Sheridan]

We keep seeing this warning for our Azure tenancy health: "Critical domain WebSocket connectivity failures detected in your tenant"

 

The warning also says: "Current status: We've detected WebSocket Secure (WSS) failures to the following unified domains: *.cloud.microsoft and *.office.com"

 

I don't understand this as we effectively have those domains whitelisted/bypassing https inspection etc and everything seems to be working as normal. Nothing has been changed as far I'm aware

 

Anyone else seen this warning in their tenancy?

I've seen this too, URL in the allow list but its not gone away let, no noticeable issues.
