Proc http to Rave returns error

[RW9]

Hi,

I am attempting to retrieve CSV files from Rave via proc http.  This work via browser, i.e. post uri, enter login, it downloads the csv file.  However when I run proc http with same uri and login details I get the following error message:

ERROR: Windows SSL error -2146892018 (0x80090326) occured at line 2320, the error message is 'The message recieved was unexpecedly or badly formatted." 

ERROR: Windows SSL error -2146892018 (0x80090326) occured at line 2320, the error message is 'The message recieved was unexpecedly or badly formatted."

Error: Encryption run-time execution error

Note that the code is run on destktop SAS version 9.4 1M2 running on Windows 10 Enterprise. 

In a previous role we had this code working correctly, although we did have to add proxyhost and proxyport in. 

Is this something that anyone else has encountered or come up with a solution for?  Is it related to needing proxy information as our IT state there is no proxy.
