# 550034: CloudApp auth rate limited

Log Type: TWILIO

Log Level: ERROR

## Description

The CloudApp provider is rate-limiting authentication requests from Twilio. The provider has temporarily blocked additional login or token-refresh attempts because too many authentication requests occurred in a short period. This issue affects only the authentication flow and is different from an API quota error.

### Possible causes

* Several datasets share the same CloudApp user credentials, which generates a high volume of concurrent token-refresh or authentication requests.
* Short sync intervals across many datasets trigger simultaneous authentication attempts that exceed the provider's per-user authentication rate limit.
* An earlier authentication-failure loop repeatedly retried the provider's authentication endpoint.

### Possible solutions

* Reduce how many datasets you sync at the same time when they share the same CloudApp credentials.
* Stagger sync schedules across datasets to prevent simultaneous authentication bursts.
* Where supported, configure OAuth with a dedicated service account or use a long-lived API token instead of username/password authentication. This configuration reduces token-refresh frequency.
* Wait for the rate-limit window (typically a few minutes) to expire, and then retry the sync. Twilio will also retry automatically based on the configured retry policy.
