How do I resolve the “Connection Failed” error when using the Citrix client?
This error is because the default setting for the Connection type is set to TCP/IP + HTTP, instead of just TCP/IP. To change this setting, browse to your Applications folder, then to the Citrix ICA Client Folder. – Launch the Citrix ICA Client Editor. – On the Network Connections tab, click on the “Default Settings” button towards the bottom left. On the “Making a Connection” tab, you will see an area for Network Protocol. – Click on the drop down box and change the setting from TCP/IP + HTTP to just TCP/IP. – Save your settings and try connecting again.
