Web servers are a complex matter. Not configuring them properly can undermine your security, and can lead to risks of suboptimal performance with PeerTube.
We made the choice to support only one web server officially (Nginx), so that we can focus on it. You can however find here user-contributed configurations. Be advised that there will be no support for problems related to them, and that bugs still need to be replicated with the official web server when opening an issue.
Apache2/httpd
