- Check that all published DMS ports are actually open and not blocked by your ISP / hosting provider.
- SSL errors are likely the result of a wrong setup on the user side and not caused by DMS itself.
- Ensure that you have correctly started DMS. Many problems related to configuration are due to this.
!!! danger "Correctly starting DMS"
Use the [`--force-recreate`][docker-docs::force-recreate] option to avoid configuration mishaps: `docker compose up --force-recreate`
Alternatively, always use `docker compose down` to stop DMS. **Do not** rely on `CTRL + C`, `docker compose stop`, or `docker compose restart`.

DMS setup scripts are run when a container starts, but may fail to work properly if you do the following:
- Stopping a container with commands like: `docker stop` or `docker compose up` stopped via `CTRL + C` instead of `docker compose down`.
- Restarting a container.
Volumes persist data across container instances, however the same container instance will keep internal changes not stored in a volume until the container is removed.
Due to this, DMS setup scripts may modify configuration it has already modified in the past.
- This is brittle as some changes are naive by assuming they are applied to the original configs from the image.
- Volumes in `compose.yaml` are expected to persist any important data. Thus it should be safe to throwaway the container created each time, avoiding this config problem.
