Hi John,
I had some problems when dealing with https and certificate name mismatch.
Not sure if it's your case. Anyway, my problem occured because I'm behing a
reverse proxy with multiple certificates and python 2.7 does not like this.
The problem should be solved by the SNI (Server Name Indication),
implemented in python 3. But that is not used by Geonode yet.
I opened an issue about this, just in case:
https://github.com/GeoNode/geonode/issues/2695
Cheers
Daniel
