Fix Steam Error Code 105, ‘unable to connect to server’




Steam has been a very popular gaming platform worldwide. With the new Steam Deck handheld gaming machine, we expect millions more to join. This platform is used by many gamers all over the globe to download, buy and play games. You can also find games and special offers in the store.

Steam has its faults, even though it is a popular service. While the service runs smoothly, for the most part, there are instances when Steam users report that they have encountered issues that cause them to panic, particularly if it affects their gaming experience Error code 105 is the latest issue.

However, it is not a major problem. Our extensive investigation has shown that Error code 105 can be fixed with relative ease.

Error code 105: Unable to connect server. The server might be offline or not connected to the internet.

What are the causes of Steam Error Code (105)?

I received many questions about Error Code 105 from users around the world. It is the main reason for the users’ misery and makes their nights miserable.

My research revealed that the three most common causes of the Steam error code 105 are:

1. Faulty Internet Connection

The reason for the Steam error code105 is due to a network connection issue. If you don’t have an ideal internet connection, the Steam error code 105 will be displayed. This is because the slow internet connection between the user (and the server) causes the error code to appear.

2. Adblockers

You already know that ads are the main source of income for websites. Users cannot block ads from any website. Some users use Adblocker to prevent unwanted content from being blocked so they can continue playing the game without interruptions. 

Sometimes, however, these Adblockers can cause Steam error code105. They block all unwanted stuff, but they sometimes also block access to Steam’s store, which can lead to error code105.

3. DNS Configurations

DNS. I’m sorry that you are unfamiliar with this term, but it is not more than an internet phonebook. If you have set up DNS, you will only be able to connect to the server. Otherwise, you will have to deal with Error Code 105 Steam.

The Steam client has a bug where Ad Blockers installed on it interfere with it and stop certain features from functioning properly.

Solution 4 – Modify your DNS

DNS can also cause an error code 105 Steam. High-speed DNS is recommended because so many people use the DNS of their Internet service provider. 

These are usually slow because of their server.

This issue can be fixed by switching to public DNS. Public DNS includes Google, Cloudflare, and many others.

These steps will allow you to modify your DNS.

Windows Devices

  • After opening the “Run”, type ” ” and click OK.

  • Log in to the router control panel.
  • Go to the internet section. Make sure you set your static IP as your internet connection type.
  • Now, place in the primary section and in secondary DNS.
  • Click the Apply button.
  • Now restart your router.

Solution 5 – Check Steam for Downtime

Also, verify if Steam servers have gone down.

Solution 6 – Updating Web Browser and Steam App

It is important to ensure that your browser is up-to-date. If you have an outdated browser, the results you see are unlikely to be accurate.

You should also update the steam app from time to time, as some games cannot be played without it.
