I always receive the following errors due to some misconfiguration. It can be easily solved.
Your account cannot be added using this server address.
Make sure you entered it correctly.
An SSL connection to the server coudn't be established because the server's certificate was not trusted.
To solve this issue, execute the following command and restart Citrix Receiver.
$ sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
$ sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/
