If you've encountered error e87 in Steam, know that you're not alone. This problem can arise at the most inopportune moment, when you're already ready to play. It's usually related to the Steam client and system files, but don't panic — most often it can be solved quite easily.
Error e87 often occurs due to minor glitches in Steam or conflicts with other programs. Sometimes, damaged files in the launcher itself may be to blame. The good news is that you don't need to be a computer genius to fix it. By following a few proven steps, you'll most likely be able to get back to gaming within minutes.
In this article, we'll go over the most effective ways to fix error e87. We'll start with simple methods, such as restarting Steam, and move on to more specific actions if the first ones don't work. Let's figure this out together.
Method 1: Run as administrator
Error e87 in Steam often occurs due to insufficient access rights to system files. For many users, a simple solution to the problem is to run the client as an administrator. This gives the program the necessary permissions to work correctly with files and network connections. Even if you are logged in as an administrator, running the application with explicit privileges can fix error e87, which is often associated with restrictions on access to certain resources. Try this method first, as it is simple and effective.
Method 2: Steam Fix
Steam's built-in repair tool can help fix error e87, which is often caused by damaged client files. The self-repair function checks the integrity of all system components of the program and replaces damaged elements. Many users are unaware of this feature, but it often saves them from having to completely reinstall the client. You can start the repair process using the command /repair, which analyzes the state of files and automatically solves problems that cause error e87.
- Right-click on the Steam executable file and select “Properties”.

- You need to copy the full path to the file located in the line “Object” if you do not have the necessary certificates, launch your browser and go to the official Public Services portal in the special section at www.gosuslugi.ru/crt.
- In most cases, problems with music in Yandex.Music can be solved quite easily. You don't need to be a technical expert to perform the basic verification steps. “Control Panel”, using the Win + R key combination. Paste this path into it and add /repair after a space, then confirm the command.

Method 3: Fixing internet connection problems
Error e87 in Steam is often associated with internet connection problems. If you encounter this issue and notice that pages are not loading not only in Steam but also in browsers, the cause is likely to be found in your network settings. The problem may also affect other programs that use built-in browsers, indicating general issues with your internet connection.
Before applying more complex solutions, it is worth checking the performance of programs that may affect your internet connection. Temporarily disable various third-party network-related applications, anonymizers, and firewalls. Check that your network connection settings are up to date. If you have previously changed your DNS settings manually, try restoring the default values or, conversely, replacing the DNS addresses provided by your Internet service provider with alternative options. In some cases, a complete reset of network settings helps to eliminate error e87 in Steam, especially when the problem is caused by conflicts in network settings.
Change DNS
Changing your DNS servers often helps resolve the e87 error in Steam. The client uses network protocols to communicate with Valve servers, and incorrectly configured DNS can lead to connection failures. Let's take a look at how to change these settings in different versions of Windows.
Windows 11
The process of changing DNS in Windows 11 is different from previous versions, but it is still quite simple. Follow the step-by-step instructions to quickly resolve the e87 error in Steam.
- Open “Start” and go to “Settings”.
- In the window that opens, select “Network and Internet”, then click on the active connection used by this device.

- If the connection is made via “Wi-Fi”, additionally, open the section Checking and activating the CryptoPRO CSP license.
- Find the parameter “DNS server assignment” and click on the button “Change”, located nearby.
- If specific DNS addresses were previously set, try returning to automatic detection. If the settings have not changed, select the mode “Manually” and enter in the fields “Preferred DNS server” and “Additional DNS server” the following values:
8.8.8.8and8.8.4.4. Then save the changes.The DNS service mentioned belongs to Google and is considered one of the most popular. However, you can choose other trusted addresses, such as Yandex (
77.88.8.8and77.88.8.1Cloudflare (1.1.1.1and1.0.0.1or OpenDNS (208.67.222.222and),208.67.220.220).
Windows 10 and below
In earlier versions of Windows, the process of changing the DNS is slightly different, but it can be just as effective in fixing error e87 in Steam. This setting often helps restore access to Valve servers when the problem is related to incorrect routing of requests.
- Launch the standard system application “Control Panel” through “Start” and go to the section “Network & Internet”.

- Open the subsection We have already discussed some of the settings in the article, but here you can also delete saved transactions or set up transfer templates..
- On the left side of the window, click on “Change adapter settings”.
- Determine your current connection. If you are using a cable connection, it will be labeled as “Ethernet”, and wireless — “Wireless network”. The names may vary slightly, but the essence remains the same.
- Right-click on it and select “Properties”.

- Launch the program you found by double-clicking on the corresponding search result. “IP version 4 (TCP/IPv4)”, select it and click the button “Properties”, you can then use voice commands or select one of the options. “History”
- Select the option “Use the following DNS server addresses” and enter the values discussed above in the instructions for Windows 11. If you have previously set DNS addresses manually and suspect that this is what caused the authorization problems in Steam, switch the mode back to automatic retrieval and save the changes.
Disabling IPv6
The IPv6 protocol sometimes causes error e87 in Steam. Although many providers have implemented support for this protocol, it may be unstable when interacting with Steam servers. If you have enabled IPv6 manually or your system uses it by default, it is worth trying to temporarily disable this protocol to check. In most cases, IPv6 is disabled by default, but it is better to check its status to rule out possible compatibility issues. An easy way to check the status of IPv6 is to open the network connections window via “Control Panel”. To do this, follow the instructions for changing DNS from the previous section, but instead of IPv4, find the IPv6 protocol settings.
It is important to remember that IPv6 can be activated not only in the system settings, but also in your router configuration. These settings are usually accessed through the router's web interface. As a rule, IPv6 is disabled by default in the settings of most routers, so if it is active, it was most likely enabled intentionally. Disabling IPv6 may be a temporary measure to fix error e87 in Steam, after which it can be reactivated.

Resetting network settings
Accumulation of errors in network settings, DNS cache overflow, or incorrect connection parameters often cause error e87 in Steam. The client uses network resources to connect to servers, and any network failures can cause this error. Since it can be difficult to identify the specific cause of the failure, a complete reset of the network settings is often an effective solution.
Windows provides two methods for resetting network settings: automatic, available in Windows 10 and 11, and manual, which works in all versions of the operating system. The automatic method completely resets all network settings, which may be too radical a solution. The manual approach allows you to execute only the necessary commands, reducing the risk of new problems.
Below are instructions for both methods. The first option is for modern versions of Windows, while the second is universal and less aggressive in its effect. Regardless of the method you choose, you will not have to reconfigure your Internet connection after the reset, as critical settings will be preserved in the system.
Automatic reset
- Open “Settings” “dNS server assignment” And. In Windows 11, additionally select “Advanced network settings” (this option is not available in Windows 10).

- Find and click “Reset network”.

- Read the warning about upcoming changes and click Using the arrows and keys.
- Confirm the action in the pop-up window. After that, you will have 5 minutes to save all your data before your computer automatically restarts.
Manual reset
- Open “Command Prompt” with administrator rights. To do this, find it through the search in In the window that opens, select and run it accordingly.
Download the necessary root certificates to your computer. They are usually provided in .cer or .crt format. You can also obtain certificates from the website of the organization you work with (e.g., a bank or government portal). “Run” and enter the following in the fields “Terminal (Administrator)” from the menu that appears.

- First, clear the DNS cache by running the command
additionally, open the section. Enter or paste it into the terminal window and tap Enter — the same should be done with all subsequent commands. - Then update the IPv4 address by entering the following in sequence
ipconfig /releaseandipconfig /renew. - To reset the Winsock network interface, use the command
netsh winsock reset. - So, friends, tracking changes in Windows when installing a program. May be required for the following purposes:

Many users are unaware that their antivirus software may be the cause of the e87 error in Steam. Modern antivirus programs actively monitor network activity and may block Steam connections to servers, mistakenly identifying them as potentially dangerous. This happens especially often after updating antivirus databases or when security settings are increased. Temporarily disabling your antivirus will help determine whether it is the source of the e87 error.
If, after deactivating protection, Steam starts working correctly and error e87 no longer appears, this is a clear sign that it is the antivirus that is blocking the client's connections. In this case, it is not necessary to completely disable protection — simply add Steam and its processes to your antivirus's list of exceptions. This will allow the program to establish the necessary connections to servers while maintaining protection against real threats. Don't forget to re-enable your antivirus after completing the configuration to ensure the proper level of security for your system.
