Connection Point Server Disconnected

Hello
I am new to SCCM and just noticed the issue shown in the screenshot.

The screenshot is from the Admin console connected to our SCCMMEM host. We have a SCCMDP01 and 02 hosts as well. I have verified that all three can ping each other and access the internet.

The three hosts are on on prem. I would be extremely grateful for some advice to troubleshoot the issue shown in the images.

As far as I can tell there's no impact, so I'm confused about the meaning of the error and how to fix.

It was Connected, and has changed to Disconnected at some unknown time...
