I was trying to access the R code for Request Response API after deploying a ML Model as web service.
I am using the code -
response = httr::POST(url= some url, add_headers("Content-Type" = "application/json", "Authorization" = authz_hdr),
body = body)
But in return, I am getting an error Error in curl::curl_fetch_memory(url, handle = handle) :
Failed to connect to ussouthcentral.services.azureml.net port 443: Connection refused
is it because I have the free version of the azure ML workspace ?
