 Additionally, if you are using temp admin method to deploy, to prevent confusion, the value of `SYNO_HOSTNAME` must targets to current local machine (can be `localhost` or `127.0.0.1`), however if your custom SYNO_HOSTNAME does indeed target to current local machine, you should execute `export SYNO_LOCAL_HOSTNAME=1` before deploying.
