Some messages to Signal users failingNotification Sender

We're currently unable to send Signal messages to some Signal users (first-time messages to users that we have never sent messages in the past). The error messages from Signal indicate a rate-limiting issue. Previously, we could temporarily work around the rate-limiting by manually solving a CAPTCHA, but currently the issue persists even after solving CAPTCHA.

The Signal servers apply rate-limits per sender account, and, obviously in retrospect, also per sender IP. If server A hits a rate-limit, and we submit a CAPTCHA solution from server B, it will not work. We're making changes on our side to take that into account.

The issue is resolved.
