Web proxy settings
Your Moodle server may need to access the Internet through a proxy server, depending on your network configuration. If you're not sure about whether you need a proxy server, contact your network administrator or ISP.
Internet access on server is required for many core features such as:
- language pack installation and upgrade
- automatic updates
- messaging plugins
- timezone updates
- server environment check before upgrades
