TURN Client Error
connectivity
The connection has been rejected by the TURN server due to a client error (4xx).
Description
This indicates that a TURN server returned a client error response.
Usually, these will be 403 (Forbidden), 440 (Address Family not Supported) or 442 (Unsupported Transport Address).
Here is what to do in each of these cases:
- 403 Forbidden - usually, the IP address of the client was rejected on the TURN server due to a policy
- 440 Address Family not Supported - when the TURN server doesn’t support IPv4 or IPv6 and asked to provide such an address type
What do we do here?
When we see a 4xx error on TURN (other than 401) we mark it as an Observation.
