HTTP 600 while downloading files from BLOB using HTTPS


  • I am using Azure BLOBs to store hex files. When I am trying to download these using SIM908 modem I am getting HTTP 600 along with following message: "No HTTP PDU".  While downloading same file using HTTP endpoint everything works.  

    Another interesting point is if HEX file is less then 900 bytes then download is successful even over HTTPS, but consistently fails for anything larger than that. 

    Any advise or pointers will be appreciated.

  • Hi,

    Have you configured Azure Storage connection Strings?

  • Hi Malar-

    Thank you for your response. Just to clarify we are using uploader component in our MVC websites which allows users to upload files to BLOB. This part works great! Now when end users using SIM908 modems (hardware) are trying to use regular HTTPS to download these files it fails if file is large, but works if file is small.  Here we are just talking about issuing HTTP GET request. 

    Can you elaborate on your advise for connection Strings, as I am not sure how its related

    Thank you,
