go to post Tom Philippi · Apr 20, 2017 Thanks! We just needed to install the certificates on the web server and not in InterSystems. Being able to configure SSL / TLS as a server with appropriate clients is somewhat confusing here because that can't be used for the web server and was also not clear from the documentation.
go to post Tom Philippi · Mar 18, 2017 I have found the problem.in the configuration of the adapter I set the server address to http://mandrillapp.com. I changed it to mandrillapp.com (without http://) and it worked!
