Port 8008 is forwarded in our case, so unless we adjust
`x_forwaded` for it, Docker's local network IPs are
logged/displayed for devices.
The TLS port (8448) is not proxied in our setup,
so its `x_forwarded` setting remains `false`.
Otherwise certains values in the config file,
such as `macaroon_secret_key`, would be regenerated,
which is not something that we want.
If `macaroon_secret_key` is regenerated, all users'
auth tokens will become invalid (effectively logging out
all users).
