I got a reply from our ITD group. They claim to have fixed the issue. As it worked for me before, I can't easily verify it.
Please, give it a try now. For the curious, the problem was on the reverse proxy side of configuration.

    Ok, I have managed to find a bit more.

    "The certificate is signed with an intermediate CA certificate from one of the well known CA's and the remote server is misconfigured in the regard that it doesn't include that intermediate CA certificate as a CA chain it's response."

    Specifically it looks like extra downloads are needed to navigate from "InCommon RSA Server CA" to "USERTrust RSA Certification Authority" (which is in our ca-bundle.crt file).

    I guess curl seems to need a bit more help from the server.  Hopefully this will be easy enough for the epics.nsls2.bnl.gov administrators to fix?
