We have about 10 certificates that were renewed today and are giving the below error on the Qualys SSL Test. Similar server signature errors show on our internal monitoring tool. One of the domains is https://www.canadalightingexperts.com/ and a url to test manually in a browser is https://www.canadalightingexperts.com/secure/login.aspx I do not see any outages on the status page or reports of similar recent issues from other users.
