SSL error during login on windows

Hey all,

when I try to connect to DataSHIELD via a windows-based system I receive the following error:

Logging into the collaborating servers
Error in function (type, msg, asError = TRUE)  : 
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

From a little bit of research I know that this error rises in the openssl lib under windows. I’m experiencing this issue for quite a while now and have always switched to my Mac for working with DataSHIELD. However, I wanted to ask if anybody here knows a solution so that a connection from windows based system is also possible.

PS: Connections via HTTP are possible is always working, the error only rises on secure connections.

Best regards, Patrick

By using DSI package from Github it is now possible to connect via windows

Exactly. Current official datashield release is based on legacy opal R package which itself depends on RCurl which is not maintained. The coming “DSI” version is based on opalr, available in the CRAN and based on httr (which is a very reliable package).
