General

Settings > General has sections for Host, Security, Proxy, Logging and Backups. Security has its own page.

Host

Setting	Default	Effect
Bind Address	*	Address to listen on. Needs a restart
Port Number	5173	Needs a restart
URL Base	empty	A path prefix, for reverse proxy sub-folders such as /audiobook-manager. Needs a restart
Instance Name	Audiobook Manager	Shown in the tab and used as the syslog app name
Application URL	empty	The external address, including http(s)://, port and URL base
Enable SSL	off	ABM serves HTTPS itself. Takes a certificate path and a key path. Needs a restart

In Docker the environment variables PORT and the compose port mapping are what matter in practice. See Environment variables.

Proxy

How ABM reaches the internet for metadata, covers and Audible pages.

Setting	Default	Effect

The section also shows your outgoing IP as external services see it. A choice of connection, including a built-in VPN, is planned for a later release.
