Server certificate checking occurs for connections between Horizon Client and a server. A certificate is a digital form of identification, similar to a passport or a driver's license. Your system administrator might ask you to set the certificate checking mode in Horizon Client to make sure that you can successfully connect to a server.
At some companies, an administrator might set the certificate checking mode and prevent you from changing it in Horizon Client.
Procedure
What to do next
If you receive a certificate error after setting the certificate checking mode, contact your system administrator.
