Hi,
to harden the firewall, is there some documentation, which outgoing connections Matomo requires? I know it’s possible to configure a proxy, but I’d like to know the exact hostnames/URLs Matomo needs to connect, so that anything else can be blocked.
Any help would be appreciated. Thanks.
There isn’t really a list of hosts, but https://matomo.org/faq/troubleshooting/faq_16646/ contains a rough list of things Matomo uses the internet connection for.
Most importantly are api.matomo.org (for updates), https://builds.matomo.org/ (for downloading updates) and plugins.matomo.org for the marketplace.
But there are also other requests like the GeoIP Database updater and updating the referrer spam list from https://raw.githubusercontent.com/matomo-org/referrer-spam-list/master/spammers.txt
So unfortunatly there is no complete list, but with those ones you should have the most important things working.
