I have been connecting to this site for a while without problems (an online gradebook for son's school), but yesterday when I tried to log in from home machine, I got the "This connection is Untrusted" error message. However, I was able to log in without a problem from work today, but having the same problem at home again. Is it an indication that my home connection is somehow compromised? How do I check? Other sites seem to working fine.

Is that server sending all intermediate certificates?

You can inspect the certificate chain via a site like this:

I actually added a temporary exception, and it seems to have fixed the problem. And your site says it's trusted too. So all is well, thanks for the suggestion.

It is usually better to install missing certificates by visiting another website that sends them then by making an exception.
You can check the certificate chain on the working computer by clicking the Site Identity Button (favicon) on the location bar > More Information > View Certificate > Details and export missing intermediate certificates and import them on the other computer.

You can remove exceptions on the Servers tab in the Certificate Manager.
