How do I configure multiple intermediate certificates?

I was able to get this working. There must have been something wrong with one of the certs in the intermediate chain or the name "intermediate-ca" is reserved in some way.

 

 

I redownloaded each of the certs, exported to base 64, reconstructed the intermediate chain file and imported it as a new Cert Bundle.

 

 

There is nothing different from the new chain file and the old one, except that I named the new chain file something other than intermediate-ca.
