 1. Make sure to exactly follow the whole reverse proxy documentation step-for-step from top to bottom!
 1. Find out if you can ping the private ip-address of the host that is running the docker daemon from inside the reverse proxy container (if runing the reverse proxy in a container). **Advice:** the `nextcloud-aio-mastercontainer` is **NOT** running the docker daemon. The host itself is running the docker daemon.
 1. Try to configure everything from scratch if it still does not work!
-    <!-- - If not, you need to make that possible. In worst case, you need to use the `--network host` option when starting the reverse proxy container (if the reverse proxy is running inside a container) -->
+1. If nothing works and as last resort, you can modify `<private.ip.address.of.the.host>` to `localhost`. For that to work, the reverse proxy needs to be member of the host network. That means, that when running the reverse proxy inside a container, you need to use the `--network host` option when starting the container.
