- Name it as RDGClientTransport.
- Double-click on it to set the Value data as 1.
- Click the OK button and restart your computer.
After that, you won’t see the error anymore.
2] Remove invalid binding
An invalid site binding could also be responsible for this error. Therefore, it is recommended to remove all the invalid binding from the IIS Manager. For that, you need to open the IIS Manager first. Then, go to the Default Web Site and select the Site Bindings.
Following that, right-click on the invalid binding and choose the Delete option.
3] Temporarily disable firewall
At times, an incorrect setting in the Windows Firewall could also cause the same error. This error mainly occurs when users install third-party firewall software. If you have done the same thing, you can temporarily disable the firewall software and check if it resolves the issue or not.
4] Verify SSL certificate
An SSL certificate is involved when you are using the Remote Desktop Protocol or RDP. No matter which SSL certificate you are using, it might be corrupted or might not be working correctly. That is why it is recommended to verify the SSL certificate before heading toward other solutions.
5] Verify DNS of Remote Desktop Gateway server
Like SSL, you must verify the DNS of the Remote Desktop Gateway server’s FDQN. This checkup includes all the DNS records, IP address, TCP port, etc. If all the settings are not set correctly, it is recommended to do that before re-trying.
