Session ID not valid

I am trying to create a talk stream but keep getting a 'missing or invalid session_id' message.

The webrtc connection is established.

I am trying to use the session_id returned from the 'create new stream' call.

I am trying to use the session_id in less than 2 minutes of receiving it.

Below is an example of the session_ID I have used and failed:

AWSALB=7gOvgHZZuHEtuoTmKoAiEgedKMIM2Z5kmX6mRV+M6TlSbr2oakotglAPBbQVPIS2hUTab465+gRvtP9SWyNm1E+86xNh2t5qhDNN5ZJoznlpELu9QcxAXgGPK8nq; Expires=Tue, 23 Jul 2024 15:14:38 GMT; Path=/; AWSALBCORS=7gOvgHZZuHEtuoTmKoAiEgedKMIM2Z5kmX6mRV+M6TlSbr2oakotglAPBbQVPIS2hUTab465+gRvtP9SWyNm1E+86xNh2t5qhDNN5ZJoznlpELu9QcxAXgGPK8nq; Expires=Tue, 23 Jul 2024 15:14:38 GMT; Path=/; SameSite=None; Secure"

I was successfully able to make this call previously, but it was intermittent and occasionally failed. Now it is failing all the time.
I have sufficient credits.

Any help would me much appreciated!
