To troubleshoot connection issues:
Check network connectivity: Ensure both the remote and local computers are connected to the internet.
Firewall settings: Verify that the firewall is not blocking the Remote Desktop or remote access ports (usually port 3389 for Windows RDP).
IP address: Confirm you are using the correct IP address or hostname.
Remote access permissions: Ensure remote access is enabled on the target computer.
Software updates: Check for updates to your remote access software, and update if necessary.
Restart the remote service: If possible, restart the Remote Desktop service or the entire system to reset the connection.
