Fix Steam Remote Play Not Working

Steam Remote Play lets you stream games from your main PC to another device, but when it stops working, it’s usually due to network settings, firewall rules, or outdated client versions. This guide walks you through the most common fixes, from basic checks to advanced router configuration, so you can get back to playing remotely.

What You’ll Need

Access to the Steam client on both the host and client devices
Administrator rights on the host PC (to change firewall settings)
Router login credentials (if you need to forward ports)
Both devices connected to the internet

Step-by-Step

Check Steam Client Updates
On both the host and client devices, go to Steam > Check for Client Updates. If an update is available, install it and restart Steam. Remote Play features are often improved or fixed in these updates.
Enable Remote Play on the Host
On the host PC, open Steam, go to Settings > Remote Play. Make sure “Enable Remote Play” is checked. Also, ensure the host is not in offline mode (Steam > Go Online).
Test on the Same Network First
Connect both devices to the same local network (e.g., same Wi-Fi router). Try streaming from the client device. If it works locally, the issue is likely network-related (NAT, firewall, or internet speed). If it fails locally, the problem is with the host setup.
Adjust In-Home Streaming Settings
On the host, go to Settings > Remote Play > Advanced Host Options. Try changing the video capture method (e.g., from NVIDIA NVFBC to software encoding) or disabling hardware encoding temporarily. Also, set the streaming quality to “Balanced” or lower to reduce bandwidth demands.
Check Firewall Permissions
On the host PC, open Windows Defender Firewall (or your third-party firewall). Ensure Steam is allowed on both private and public networks. If you see Steam listed, remove it and re-add it by running Steam as administrator once. For third-party firewalls, add exceptions for Steam and the game you’re streaming.
Port Forwarding (for Internet Streaming)
If streaming over the internet fails, log into your router and forward the following ports to the host PC’s local IP address:
TCP 27036, UDP 27036, UDP 27031-27036. Also, enable UPnP in the router settings if available. After forwarding, restart the router and the host PC.
Disable VPN or Proxy
If you use a VPN or proxy on either device, disable it temporarily. Remote Play requires a direct connection; VPNs can interfere with the handshake.
Update Graphics Drivers
Outdated GPU drivers can cause encoding issues. Visit the GPU manufacturer’s website (NVIDIA, AMD, Intel) and install the latest driver for your hardware.
Restart Everything
Restart both devices, the router, and Steam. Sometimes a simple reboot clears temporary glitches.

Common Mistakes

Host in offline mode: Remote Play only works when the host is online on Steam.
Firewall blocking Steam: Even if Steam is allowed, some games add their own firewall rules; ensure the game executable is also allowed.
Using a VPN: VPNs can cause high latency and connection failures; always test without.
Incorrect port forwarding: Forwarding to the wrong IP address (e.g., a laptop instead of the desktop) is a common error.
Too high streaming settings: Setting 4K or 60fps on a slow connection will cause stuttering or disconnects.

Tips

Use a wired Ethernet connection on the host PC for stable upload speeds.
Close bandwidth-heavy applications on the host (e.g., downloads, cloud sync) while streaming.
On the client, lower the resolution and disable vsync to reduce input lag.
If using a laptop as client, keep it plugged in; power-saving modes can throttle performance.
For internet streaming, check your upload speed (at least 5 Mbps for 720p, 15 Mbps for 1080p).

Troubleshooting

If Remote Play still doesn’t work after these steps:

Check Steam status: Visit the Steam Stat page to ensure the Remote Play service isn’t down.
Try a different client device: If possible, install Steam on a phone or another PC and attempt to stream. This isolates the issue to the original client.
Reset Steam settings: On the host, go to Settings > Remote Play and click “Restore Defaults”. Then re-enable Remote Play.
Check NAT type: In the router, ensure NAT is set to “Open” or “Full Cone”. Strict NAT can block incoming connections.
Use Steam Link hardware: If you have a Steam Link device, try it. If it works, the issue is with your client software.
Contact ISP: Some ISPs block certain ports or use carrier-grade NAT, which prevents port forwarding. Contact them to ask if port forwarding is supported.

Frequently Asked Questions

Why does Remote Play work on my home network but not over the internet?
This usually indicates a NAT or firewall issue. Ensure port forwarding is set correctly and that your ISP doesn’t use CGNAT. Also, check that your upload speed meets the minimum requirement.

Can I use Remote Play with non-Steam games?
Yes, you can add non-Steam games to your library and then use Remote Play. However, some games with anti-cheat may block streaming.

Why is my stream laggy or stuttering?
Lag is often due to insufficient bandwidth, high latency, or too high streaming settings. Lower the resolution and bitrate, and ensure both devices are on a stable connection.

Does Remote Play work on macOS or Linux?
Yes, Steam Remote Play is available on Windows, macOS, Linux, Android, iOS, and even some smart TVs. The host must be on a supported OS (Windows, macOS, or Linux).

Why does the client show “No computers found”?
This means the client can’t see the host. Check that both are logged into the same Steam account, the host is online, and Remote Play is enabled. Also, ensure the firewall isn’t blocking the discovery protocol (UDP 27036).

Can I use Remote Play while someone else is using the host PC?
Yes, but the host user will see the game launch and may be interrupted. Remote Play streams the host’s screen, so any other activity will be visible to the client.
