Self-Hosted Docker: Unable to use webhooks with other services on the server

I used webhooks to perform actions with other services running from the same compose file (manage cache, etc). I’ve been unable to do that since March when this PR was merged: Added IP format normalization to request-external by kevinansfield · Pull Request #26717 · TryGhost/Ghost · GitHub

Does anyone have suggestions on how to use webhooks with local services? I’ve tried local hostnames, but since it continues to resolve to a local IP, I get the same error.
