I am using RStudio to connect to a remote URL using HTTPS. The remote server is configured to allow protocols TLSv1.1 and TLSv1.2.
This results in the following error:
Error in function (type, msg, asError = TRUE) :
Unknown SSL protocol error in connection to my.domain.com:8443
When I enable TLSv1, however, the connection works.
I am running RStudio version 3.5.1 on Windows 7 Pro SP1 64 Bit. To the best of my knowledge, Windows 7 supports TLSv1.1/2. Is there a setting or option within RStudio that is required?
