Hey,
Assuming that the shared hosting is still running on a VPS and not somewhere I can directly access, are you able to add the following?
"Transport for NSW": [
"147.200.0.0/16"
]
Sidenote, if we refactor config to separate credentials from other config, then we could keep the bot configs (ranges, whitelists, etc) versioned in git, which would make it easier for others to see & suggest changes.
