I am running domain mapping on a multisite network which contains a UCC SSL certificate with Subject Alternative Names. On the root domain and non-mapped subdomains, the SSL connection works fine. However on mapped domains it is dropping out of SSL. If I try to force SSL (with a plugin like Wordpress HTTPS), I get into a vicious cycle of dropping/forcing/droping/forcing/etc until it finally gives up and throws an error.
Is there something in the Domain Mapping plugin that is intentionally preventing it from staying in SSL? This was all working for quite a while, and I can't tell when it stopped working.
My root site is NimbleWebs.com. An example mapped domain is KenJustice.com mapping to kenjustice.nimblewebs.com. If you look at the details of the certificate you can see that KenJustice.com is a valid SAN.
