Netscaler Load Balanced Web Interface - Error Set Cookie Header not found in responce

I used the Netscaler 9.2 Wizard to create load balancing for Citrix Xenapp.

However after completing the wizard the Web interface monitors showed down for all my web interface servers.
Looking at the monitor i could see an error message
"Failure - Set-Cookie header not found in the response"

Checking back through the configuration i could see i had set the path to the Web interface site incorrectly.
I had missed off /auth/login.aspx from the end of the site path.

Adding the correct path and clicking REFRESH ALL then showed my web interface sites as up.
