# 53206: The Participant concurrency quota was exceeded

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when adding another Participant to a Room would exceed your account's concurrent Participants quota. Twilio Video enforces account-based quotas for Rooms and Participants to support reliable and consistent service operation.

### Possible causes

* Your account already has enough connected Participants across active Rooms that the next Participant connection would exceed the concurrent Participants quota.
* One or more Rooms are still in progress and still have connected Participants using your available concurrency.
* Your application's current traffic has grown beyond the concurrent Participants quota configured for your account.

### Possible solutions

* Complete Rooms that no longer need to stay active so their connected Participants are disconnected.
* Disconnect Participants who no longer need to remain in a Room before admitting new Participants.
* Review how many Participants your application keeps connected at the same time across all active Rooms and reduce concurrent usage where possible.
* If your expected traffic requires more capacity, contact sales to request a higher concurrent Participants quota for your account.
