I don't have preview proxy enabled, just regular mediaproxy, but just running an empty secondary instance with the same secret_key_base and then pointing mediaproxy's subdomain/path to that instance in nginx does the trick. Helps speed things up in setups like mine where I host the instance at home and proxy it to a remote server.
