Recently installed Storefront on Netscaler 10.1 (latest version) and had a strange issue while connecting my resources.
When connecting through the Netscaler and StoreFront to the application you’ll receive an error such as “Connection Error. Citrix Receiver could not establish connection with remote host. Please contact your administrator for assistance.”
Ah well, and guess what? We are the administrator ;–)
There’s a thing about the SSL-certificate, the Citrix Receiver for iOS just won’t support SHA2 hash algorithm. Cool – not. Android does work like a charm.
You need to ask your CA for a SHA1-certificate. We use DigiCert, which gives out SHA1-certificates on request. But same goes for Comodo, GeoTrust or others.
Citrix has a feature matrix that can be consulted, see here:
Note that other issues can appear too, like Android doesn’t support SAN-certificates, something I came across before.
