Below are the steps for fixing issues with Dota 2 connection problems and network errors, on your Windows 10 or Windows 11 PC or laptop.
Fix 1: Ensure Dota 2 is not being blocked by your firewall
Check that your firewall is not blocking the game from accessing the internet otherwise, you will not be able to connect online in the game. If you are using Windows Defender Firewall then you can allow Dota 2 access through your firewall by doing the following:
- Open the Windows Start menu and search and open “Windows Defender Firewall“
- Click “Allow an app or feature through Windows Defender Firewall“
- Make sure that the boxes are ticked next to Dota 2
- If Dota 2 is not on the list click on “Allow another app” and add it manually
Fix 2: Temporarily disable your security
Disable your computer’s security and see if that fixes the connection issues with Dota 2 (just remember you will not be protected while your security is disabled).
If this works then you will need to add the game to the exception list of your security to prevent future connection issues, while also keeping your PC secure.
Fix 3: Ensure Steam is up to date
- Open Steam
- Click on Steam in the top left-hand corner
- Click on “Check for Steam Client updates“
- If an update is available then it will download and you will need to Restart Steam once finished
Fix 4: Make sure Steam isn’t being blocked by your Firewall or security
If it is then add it to your Firewall or securities exceptions list. If you are using Windows Defender:
- Open the Windows start menu and search and open “Windows Defender Firewall“
- Click on “Allow an app or feature through Windows Defender Firewall“
- Make sure that the boxes are ticked next to Steam
Fix 5: Make sure there is no pending update for Dota 2 in Steam
Ensure you have the latest version of Dota 2 installed:
- Open Steam > Go to your Library and click Downloads at the bottom of Steam
- You will see Dota 2 in the list if there is an update pending
Fix 6: Make sure Metered connection isn’t enabled:
- Right-click Start menu > Settings
- Click on Network & Internet
