Please help

  1. Validate the server’s SSL certificate: The warning message “Certificate verification failure ‘self-signed certificate (18)’” suggests that the server is using a self-signed SSL certificate. If you are connecting from the FreeRDP client, you may need to configure it to trust self-signed certificates or import the server’s certificate into the client’s trusted certificate store.
  2. Check the server’s RDP settings: Verify that the remote server is configured to allow incoming RDP connections. Ensure that the Remote Desktop service is enabled on the server, and the necessary settings are configured correctly.

the problem is the pass i have to put in single quotes

oh, did you fix it?

yess you have to put the password in single quotes


I’m still not able to connect. Any input?

try administrator instead of Administrator


You can also try adding /cert:ignore, which will ignore the certificate entirely.
