We use a custom domain for our JSS (even though it it hosted on JamfCloud) due to it previously being migrated from a self-hosted JSS.

The certificate for our JSS appears to have become invalid at some point today.

We're unable to log into the JSS admin console, and I am unable to run any policy.

We cannot even bypass the warning, due to HTTP Strict Transport Security (HSTS).

I've confirmed that our custom domain name still has the expected CNAME record pointing to <our_sub_domain_here>.jamfcloud.com and the cert is for *.jamfcloud.com and expiring in 1 year, leading me to think it was just renewed by Jamf today, but incorrectly:

NET::ERR_CERT_COMMON_NAME_INVALID
Subject: *.jamfcloud.com

Is anyone else experiencing a similar issue?
