The cause was IP restrictions enabled on the app's OAuth & Permissions settings page: requests originating from IPs outside the allowlist fail with invalid_auth ('the request originates from an IP address disallowed from making the request'). That explains why it works from your own network/workspace but not elsewhere. Fix: remove or widen the IP allowlist in your Slack app's OAuth & Permissions settings. The maintainer confirmed this was the resolution. Source: https://github.com/slackapi/bolt-js/issues/2075
