How to Fix Error Code MD-DL-0 on Epic Games
Fixing error code MD-DL-0 on Epic Games is a simple step in many cases but difficult for beginners, low-educated people, or to those who never know the complex setting of Epic Games Launcher, config folder, or network connection. If you follow my given steps then you can easily check the problem and solve it. Here are the fixes you need to perform for removing error code MD-DL-0 on Epic Games Launcher.
Fix #1 – Close and reopen Epic Games Launcher
This error can appear because Epic Games Launcher gets stuck during installation process and cannot continue the download properly. Closing the Launcher and opening it again can refresh the install session and help the game installation start again in a normal way.
Here are the following steps which help you to close and reopen Epic Games Launcher.

- Click the up arrow in the lower-right corner.
- Right-click the Epic Games Launcher icon.
- Click Exit.
- Wait for a few seconds.
- Open Epic Games Launcher again and try the install.
Fix #2 – Increase the timeout value in DefaultEngine
This is the main fix which Epic Games officially gives for MD-DL-0. If the timeout value is too low then the installation package may not finish downloading in time. When you increase the HttpTotalTimeout value from 30 to 500 then Epic Games Launcher gets more time to download the package and the install can proceed normally.
Follow the steps below to easily increase the timeout value in DefaultEngine.
- Close Epic Games Launcher first.
- Go to the Epic Games Launcher installation folder.
- Open this route if it is available on your PC: C:\Program Files\Epic Games\Launcher\Portal\Config
- Find the file named DefaultEngine and open it.
- Search for the line HttpTotalTimeout=30
- Change the value from 30 to 500.
- Save the file by replacing the old file.
Fix #3 – Retry the installation after saving the config file
After changing the timeout value, you should try the installation again. This is important because the Launcher needs to use the new config setting for the next install attempt. Once the new timeout is active, the installation package may download without showing MD-DL-0 again.
You can perform the following steps to retry the installation after saving the config file.
- Make sure the DefaultEngine file is saved properly.
- Open Epic Games Launcher again.
- Go to your library or Unreal Engine install section.
- Start the installation again.
- Wait and check if the download continues normally.
Fix #4 – Check your internet connection
A slow or unstable internet connection can also create error code MD-DL-0. If the network becomes weak during the install then the package download may stop before completion. Checking your internet connection can help Epic Games Launcher download files with better stability.
Try these simple steps to quickly check your internet connection.
- Make sure your internet is working on other websites or apps.
- Restart your router if the connection feels slow.
- Avoid downloading large files from other apps at the same time.
- Use a stable Wi-Fi or wired connection.
- Open Epic Games Launcher again and test the install.
- Wait for some time and see if the download continues.
Fix #5 – Check Epic Games server status
Sometimes the problem is not from your computer or internet only. It can also happen when Epic Games servers are under outage or service issue. Epic’s Launcher troubleshooting page says users should check the Epic Games server status because if the Launcher is affected by an outage or system-wide failure, the problem may be fixed when the outage is resolved.
Here’s how you can check Epic Games server status in just a few seconds.
- Open the Epic Games server status page in your browser.
- Check if Launcher or download services are operational.
- See if there is any outage or failure reported.
- Wait until the issue is resolved if servers are down.
- Try the installation again later.
Fix #6 – Disable proxy or blocking settings if they affect downloads
Proxy settings or blocking software can stop Epic Games Launcher from downloading the installation package correctly.
