Fix: ‘Couldn’t Connect to the Remote Computer’ Steam Remote Play

The ‘Couldn’t connect to the remote computer’ issue in Steam Remote Play can arise due to missing the required Microsoft runtime libraries on the host and client systems, the Windows firewall blocking the streaming client from Steam, or other reasons.

It can also be influenced by the network type configured on the host PC. In this guide, we will outline several proven methods to resolve the issues with Steam Remote Play functionality.

1. Install Microsoft Runtime Libraries

To begin, ensure the Microsoft runtime libraries are installed on both your systems—host and client. These libraries are essential for the proper functioning of Steam Remote Play.

Remember to install the x32 runtime libraries even if you are on a 64-bit architecture.

1. Open the official Microsoft runtime libraries page by clicking here.
2. Scroll down and download the runtime libraries using the provided links.

   

3. Select and download the x86 version, regardless of whether you have an x64 system.
4. Install the runtime libraries on your PC and then restart it.
5. Check if the issue has been resolved.

2. Disable Hardware Encoding

Hardware encoding can enhance stream quality based on your GPU’s capabilities but it can sometimes disrupt Steam Remote Play.

1. Launch the Steam client on your PC.
2. Click on the Steam menu and navigate to Settings.

   

3. Head over to the Remote Play tab.

   

4. Toggle on the Enable Advanced Host Options to see more settings.

   

5. Disable the Enable hardware encoding option.

   

6. Restart Steam and check if the issue persists.

3. Update Steam App

A recent Steam update caused issues with remote play that were later fixed in a subsequent patch. Ensure your Steam is up to date.

1. Open your Steam client.
2. From the menu, select Steam and then Check For Steam Client Updates.

   

3. Let the client download and install any available updates, then try using Remote Play again.

4. Allow Steam’s Streaming Client through the Firewall

The Windows Defender Firewall may block network requests from Steam’s streaming client. To remedy this, add the streaming client to the firewall’s whitelist:

1. Open the Settings app by pressing Win key + I.
2. Navigate to Privacy & Security > Windows Security > Firewall & Network Protection.

   

3. Click on Allow an app through firewall.

   

4. Select Change settings.

   

5. Choose Allow another app.

   

6. Using the Browse feature, locate and select the streaming_client.exe in the Steam installation folder.

   

7. Select Network Types and ensure both Private and Public are checked.

   

8. Click OK to save the changes and add the app.
9. Check if Remote Play is now functioning correctly.

5. Change Windows Network Type

The host machine’s network type can affect the Remote Play function. Issues may arise if the network type is set to Public rather than Private.

1. Press Win key + I to open the Settings app.
2. In Settings, go to Network and Internet.

   

3. Click your active network connection, then change the Network Profile Type to Private network.

   

4. Try Remote Play to see if the issue is fixed.

6. Disable IPv6

IPV6, even if not actively in use, can still cause network disruptions. Disabling it may resolve functionality issues with Remote Play.

1. Access Settings by pressing the Windows key + I.
2. Navigate to Network and internet > Advanced network settings.

   

3. Expand your network adapter options by clicking the down arrow.

   

4. Select the Edit button in the More adapter options section.

   

5. In the Properties window, uncheck Internet Protocol Version 6 (TCP/IPv6).

   

6. Click OK, then test Remote Play once more.

7. Manually Connect to Host

If none of the above steps work, try starting the game manually on the host machine and then connect from the client device by clicking the Connect option. This manual connection method may bypass the issue.
