A little tip for people who work with Citrix StoreFront and want to secure the communication with the Delivery Controller via SSL certificates. Pay attention to the signature algorithm.
Citrix expert Julian Mooren (the Citrix Guy) points out in the following tweet that a sha256ECDSA is bridging the communication.
Watch out when securing the Citrix StoreFront and the Delivery Controller communication with a SSL certificate. If the signature algorithm is „sha256ECDSA“ this will break the communication. Stick with „sha256RSA“ and everything will work ☝

Uses a sha256RSA signature algorithm, then everything is fine. Also applies to Citrix FAS (7.15).
