 be authorized

After a series of longs hours working with AWS transcription, I now have a new error using Postman:
<AccessDeniedException>
  <Message>Unable to determine service/operation name to be authorized</Message>
</AccessDeniedException>

However, I don't know what the issue is. I tried to Google it but the error seems to happen also in AWS Lambda. But I'm working with AWS Transcription. Can anyone check what seems to be the problem?
My sample sample GET request is:
https://transcribestreaming.us-east-1.amazonaws.com/medical-stream-transcription-websocket?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=MYACCESSKEYID%2F20200404%2Fus-east-1%2Ftranscribe%2Faws4_request&X-Amz-Date=20200404T171802Z&X-Amz-Expires=300&X-Amz-SignedHeaders=host&language-code=en-US&media-encoding=pcm&sample-rate=16000&specialty=PRIMARYCARE&type=DICTATION&X-Amz-Signature=5f5f0a5d336e524b335245b6e83945d3057ec3905a9ae2d2ca709b77cce5478f

I intentionally replace the X-Amz-Credential with MYACCESSKEYID for security purpose.

A:

There maybe two errors:
1) "https://" request connects to default port of 443. This cause error of "Unable to determine service/operation name to be authorized". Please explicitly use port :8443.
2) Your client does not handle websocket upgrade correctly. In the first request to open connection, your client need initiate websocket upgrade by including several headers, as specified in "Including WebSocket Request Headers" section of https://docs.aws.amazon.com/transcribe/latest/dg/websocket-med.html#websocket-response-med
Example in curl: 
curl --include --no-buffer \
--header "Connection: Upgrade" \
--header "Upgrade: websocket" \
--header "Host:

 After a series of longs hours working with AWS arrangement, I nowadays have a new error use Postman:

 However, I don't know what the topic is. I tried to Google it but the error seem to happen also in AWS Lambda. But I'm work with AWS Transcription. Can anyone check what seems to be the problem?
