Hello Randy,
This is typically caused by the Windows 11 Pro host becoming unreachable rather than an issue with the Windows 11 Home client. Verify that Remote Desktop remains enabled, the host is not entering Sleep mode, and the Remote Desktop Services (TermService) service is running.
If you connect using a hostname, try the host's IP address to rule out DNS issues. Also check whether VPN, antivirus, firewall, or network interruptions are affecting TCP port 3389.
Harry.
