How to Fix Steam Error Code 105

Here's a look at the possible options for you to fix Steam Error Code 105.

The first thing to check is whether a fault with your internet connection that is responsible. Resetting your router, and then logging back in, is an obvious starting point.

It is also worth making sure that your connection is stable, and that you don't have too many devices and apps competing for bandwidth. If you have been using a wireless connection, you can try swapping this for a wired connection, or vice-versa.

Additionally, you could consider switching from Wi-Fi to a cellular hotspot, to see if indeed, the internet connection is to blame. If it is, and all these tips cannot remedy the error, then it might be worth checking with your ISP in case of a service issue at their end.

  • Press the Windows key and R together
  • In the run prompt, type cmd and press enter
  • Next, in the command prompt, type ipconfig/flushdns
  • Press enter
  • Once the process is complete, restart the Steam client and see if the issue has been addressed
