Fix: Could Not Resolve Host:

Short Answer

If you’re encountering the “could not resolve host:” error, it’s likely due to incorrect proxy settings, a corrupted “resolve.conf” file in WSL, outdated Docker Desktop, or firewall and “hosts” file issues. This blog will guide you through the steps to resolve these issues.

Why Does This Error Occur?

Incorrect Proxy Settings

Your Git configuration might have incorrect proxy settings, leading to this error. Make sure to update your proxy settings or unset them if they are incorrect.

Corrupted “resolve.conf” File in WSL

A corrupted “resolve.conf” file in your Windows Subsystem for Linux (WSL) can also cause this error. Deleting and regenerating this file can resolve the issue.

Outdated Docker Desktop

Older versions of Docker Desktop may have bugs in their DNS resolver, causing this error. Updating Docker Desktop can resolve this issue.

Firewall or “Hosts” File Issues

Your firewall or “hosts” file might be blocking your connection to GitHub, leading to this error. Make sure to check and update these settings.

How to Fix the Error?

Update or Unset Proxy Settings

To unset the proxy settings in your Git configuration, you can use the following commands:

bashCopy code

git config --global --unset http.proxy git config --global --unset https.proxy

Regenerate “resolve.conf” in WSL

To regenerate the “resolve.conf” file in WSL, you can use the following commands:

bashCopy code

sudo rm /etc/resolv.conf wsl.exe --shutdown

Update Docker Desktop

To update Docker Desktop, go to the system tray, click on the Docker icon, and then click on “Check for updates.”

Check Your Firewall and “Hosts” File

Make sure to add an exception for GitHub in your firewall settings and check your “hosts” file for any incorrect entries.


How do I unset my Git proxy settings?

You can unset your Git proxy settings by running git config --global --unset http.proxy and git config --global --unset https.proxy in your terminal.

What is the “resolve.conf” file in WSL?

The “resolve.conf” file in WSL is a configuration file used by the DNS resolver to translate domain names into IP addresses.

How do I update Docker Desktop?

You can update Docker Desktop by clicking on the Docker icon in the system tray and selecting “Check for updates.”


By following these steps, you should be able to resolve the “could not resolve host:” error and restore your connection to GitHub.
