HI Tominaga
Seems like you are having error with the api endpoints, Ensure that the API key you're using in the "Authorization" header is correct and hasn't expired this might be the problem. You can obtain the API key from the Azure portal by going to your Text Analytics resource and looking for the "Keys and Endpoint" section. in that section you will find 2 keys use any one of them and hopefully it works this time.
If this helps kindly upvote and accept the answer for assistance ping here thanks much.
