2. Open PowerShell as administrator
3. Enter: [System.Net.DNS]::GetHostEntry([System.Net.DNS]::GetHostName()) • Restart Citrix Workspace App

Problem Cause

 From the available log files, we can see Citrix Workspace App was unable to resolve host name via DNS and threw "No such host is known" due to it.

•  Our SelfService module was calling MSFT .NET API: System.Net.Dns.GetHostEntry() in order to resolve the host name an IPHostEntry instance, but the .NET API threw a “No such host is known” exception.
