+For OIDC and RSS feeds to work if your external access URL contains a custom port (like https://xx.yy.zz:1234/audiobookshelf/), the Host header sent by NGINX Proxy Manager is incorrect, as it doesn't include the port number. This can be fixed by adding a custom location of "/" and then opening the advanced configuration field by clicking the cogwheel. Add this additional header line here:
+
+proxy_set_header Host $http_host;
