The website "..." did not accept the certificate "unknown"

New Contributor III

When using the internet off our corporate network users are getting pesky certificate popup the states "The website "..." did not accept the certificate "unknown"". The website varies but a lot of the time its a google site like but have seen it on other sites. If you select either cert and click continue it will just reload the page with the same error 2b00344b3c7a46f1b10309e87d2bb690

Looks like the websites are not accepting the JSS built-in CA cert or our Active Direct CA cert. We use proxies that block ads so maybe its blocking the adservice site that gives a cert? I don't have a lot of experience with identities and wondered if anyone could help me out. Is anyone else was having this problem or seen it before?
