What is Remote Desktop Gateway?

Remote Desktop Gateway (RDG or RD Gateway) is a useful Windows Server role that easily allows users to connect to a server securely and encrypted using RDP (Remote Desktop Protocol). Using a point-to-point remote desktop connection, the system provides an improved level of control for remote users.

Proper configuration can enable remote users to access network resources from outside your organization through ‘untrusted networks’ and ‘in principle’ without needing a virtual private network (VPN).

What is Remote Desktop Protocol?

Remote desktops can connect to PCs using Microsoft Remote Desktop Protocol (RDP). RDP is a widely deployed, simple protocol that comes standard with the latest versions of Windows.

However, in prior versions of RDP, weak encryption techniques and a lack of access controls rendered RDP susceptible and an easy entry point for malware.

Solutions To Fix Remote Desktop Gateway server is temporarily unavailable Issue

Try out the following solutions to fix the problem of the remote desktop gateway server being temporarily unavailable on your computer.

1.Change the registry value –

It is the first thing you should check if you are experiencing the problem mentioned above of the remote desktop gateway server is temporarily unavailable on your computer. Terminal Services Client is a crucial Registry Key that must be present to utilize the Remote Desktop Protocol or RDP.

Note – We recommend using this step only if you are an advanced user and well versed with your computer, as making changes to Registry entries can cause critical issues such as system failure.

As a result, do the following actions to validate the Registry value:

Step 1: Press Win+R on your keyboard, type Regedit on the Run Command, and click the OK button.


Step 2: Registry Editor opens, find the following path –



Step 3:Right-click on the right pane under the Microsoft tab and create a New Key. Once created, right-click on it to Rename it. Give it the name Terminal Services Client.

Step 5: Again, rename it as RDGClientTransport and then double-click it to change the Value data to 1.

terminal service client tab select

Restart your computer by clicking the OK button. After that, you will no longer notice the error. If this solution does not work, try the next.

2.Examine the SSL certificate

RDG uses SSL to encrypt the communication between devices and servers. Configurations of your host (Cloudflare, for example) might corrupt your SSL certificate.

Examine your SSL certificate to ensure it is not expired. A bad SSL certificate can sometimes cause the Remote Desktop Gateway server to be a momentarily unavailable issue.

3.Disable the Firewall of the Windows

An improper configuration in the Windows Firewall might sometimes give the same problem. The remote desktop gateway server is temporarily unavailable and is most commonly seen when customers install third-party firewall software. Whether you’ve done the same, you can temporarily disable the firewall software to see if it fixes the problem.

Step 4: Hit Turn on or off Windows Defender Firewall. Select the option to disable Windows Defender Firewall. Then press the OK button.

4. Check that the FQDN of the Remote Desktop Gateway Server settles to the correct IP address

Create a local DNS record with the same Internet FQDN. Users can access RemoteApp both inside and outside by using the same rdweb.

  • TCP port 443 and UDP port 3391 must also be kept open. The other domain’s client PC packets must make it to the Remote Desktop Gateway.
  • When accessed from another domain, ensure that the FQDN, available for the Remote Desktop Gateway server, gets resolved to the exact and correct IP address for the Remote Desktop Gateway.
  • When you wish to connect, capture on the Remote Desktop Gateway server.
  • A forward lookup zone may also be easily created over the domain for your Remote Desktop Services (RDS), where you could then generate the DNS entries needed for the FQDN.

Because your server name defaults to a local machine name, the Remote Desktop Gateway server is momentarily unavailable error might occur. The PC attempting to connect must be able to resolve the RDG server’s public name. This may not be the server’s hostname.
