Expired SSL cert on Web Adaptor machine impacting registered datastores on portal?

Question

I'm trying to figure out unfamiliar territory so sorry for the lack of correct terminology (I'm a non-network admin forced to do network stuff and I'm trying to work through the ESRI support documents without much luck).

Our IT Dept has a script that tells them when certs are expiring, but somehow the GIS servers got missed.  A cert expired on our web adaptor machine, which is in the DMZ.

Now, a few of the datastores on our portal are no long accessible.  I am getting the below error from my hosting server.

Is this being caused by the web adapter machine's cert expiring?   They have issued a new cert, but now I'm not sure what I am supposed to do with it.  It's got the appropriate bindings to Port 443 from what the tell me.  Do I need to register it with the ArcGIS Server, datastore, or portal?

I'm confused because I didn't want to try and register the cert in the wrong place and screw things up.

I would make sure the certificates of each Enterprise component are still valid.  The machines running Server, Portal, and DataStore also have their own certificates. By default they are all self-signed, but your organization may not allow that.

I did run this utility and it says it ran successfully.  It did not, however, fix the error message we are getting with certain datastores now.

If your datastore is also using the same cert, then you will have to update that one as well
