Error when trying to connect to a webservice deployed with Azure Machine Learning Studio using RCurl R library RRS feed

  • Question

  • Hello!

    I recently realised that the code I was using to reach the endpoint of a webservice deployed with Azure Machine Learning Studio using the "RCurl" library from my local machine does not work anymore. 

    The webservice is deployed and it works (using any tool like Postman or  aPython script to reach the endpoint and get the output of the prediction of the model)

    The error is the following: "Unknown SSL protocol error in connection to europewest.services.azureml.net:443"

    Any help appreciated.

    Kind regards,

  • Hi Marco,

    We have updated RScore and RJobs templates, the newest templates don't use RCurl any more.
    Please update your code, from the current studio portal, you can reach to latest version of templates.

  • Thanks for the reply Lu, but when I try to access the webservice tab from my Azure ML Studio home page, I can not see my webservices listed (it is empty) and there is a link "If you don't see your webservice, click here" which redirects me to the webservice Azure page where I can see all my deployed webservices. The problem is that the R script to reach the endpoint in there is not updated and still uses RCurl

    Can you give me a link with the updated version of the templates?
