You are sending both the content length header and a chunked encoding header. This is not a valid HTTP request.

esp_http_client will take care of this for you based on the length you provide to esp_http_client_open (see https://github.com/espressif/esp-idf/bl ... 1344-L1348). Don't set either of these headers yourself.
