Steam primarily uses UDP (User Datagram Protocol) for data transmission, which is faster but less reliable compared to TCP (Transmission Control Protocol). The preference for UDP can sometimes cause connectivity errors under specific network conditions. Other possible causes may include misconfigured network settings, outdated system software, or corrupted Steam files. Before you start any troubleshooting, it’s important to check the Steam server status to confirm whether the issue is on their end. The Steam server status and user reports, which indicate real-time server performance, can be checked on websites like steamstat.us or through community platforms, and can guide you on what to do next if server issues are not the problem.
1. Start Steam in Offline Mode
This procedure is akin to restarting Steam. It has proved helpful for many users, hence its position at the start of our list. First, attempt to launch Steam, which should present the error. Then, click Start in Offline Mode. After launching Steam in offline mode, select Go Online by clicking on ‘Steam’ in the top-left corner.
2. Run Steam with TCP
Steam defaults to UDP for communication, which can lead to errors because UDP does not guarantee the delivery of data. This is why UDP is sometimes called the Fire-and-Forgot protocol. Despite UDP’s speed advantage, it can cause connection errors with Steam, making TCP a preferable alternative in certain situations. TCP ensures the successful delivery of data, resending until the data is received without problems. This can introduce latency as it includes data verification, but this typically isn’t an issue unless it impacts gameplay.
3. Restart the Network Adapter
Restarting your network adapter may resolve issues with the application. If you haven’t tried this yet, it’s worth a shot.
4. Use Google DNS
The DNS (Domain Name System) resolves domain names into IP addresses. Using a slow DNS can cause issues when connecting to servers. Google DNS is recommended due to its speed, reliability, and security. It is often advised for resolving connectivity problems.
5. Use a VPN (Virtual Private Network)
A VPN can also be used to address network-related errors. The lack of communication with the server causing this error could be circumvented by using a VPN to connect to a different route that may allow access to Steam. You can find a selection of VPN applications on our guide, available through these options.
6. Reset Network Settings
Resetting the network settings on your PC can resolve issues from misconfigured settings, such as proxies, and can also reinstall network adapters while resetting other settings like DNS. For instructions on resetting, visit how to reset network settings in Windows 10.
7. Update Windows
Outdated versions of Windows can lead to problems with Steam, so it’s worth checking for updates, particularly if it’s been a long time since your last update. If you need to stop Windows from automatically installing outdated drivers, visit our guide.
