We previously downgraded similar errors from the post metadata code, but the mobile app still uses this code path, so it can cause the server logs to be full of messages that don't need to be marked as errors.
1. On RN, make a post containing an invalid or internal URL such as `http://notarealurlatall.com/index.html`
Also test with `http://192.168.1.1/index.html` (see LM's comment below)
2. View the server logs in the system console
Expected: If you see a message like "address forbidden, you may need to set AllowedUntrustedInternalConnections to allow an integration access to your internal network", it should appear at DEBUG level, not ERROR level
