# Server base URL

{% hint style="warning" %}
If you want to delegate the SonarQube Community Build user authentication to an OAUTH provider (GitHub, Bitbucket, GitLab, SAML), you should use HTTPS for security reasons. This means that the SonarQube Community Build instance should be secured behing a proxy. See [securing-behind-proxy](https://docs.sonarsource.com/sonarqube-community-build/server-installation/network-security/securing-behind-proxy "mention").
{% endhint %}

{% hint style="info" %}
The SonarQube base URL needs to be a public URL if SonarQube expects to receive information from an external system. For more information, see [networking-requirements](https://docs.sonarsource.com/sonarqube-community-build/server-installation/networking-requirements "mention").
{% endhint %}

To configure the server base URL in SonarQube Community Build:

1. Go to **Administration** > **Configuration** > **General Settings** > **General** > **General.**
2. In **Server base URL**, set your SonarQube Community Build instance’s URL.
