In order to continue to provide a secure service, we will be disabling support for the use of the TLSv1.0 and 1.1 protocols with our API on 10/15/2019.
The 0.8.15 version of the
rsconnect package switched the default implementation for HTTP to use the curl package, which has good cross platform support for TLSv1.2. As such, starting on, or shortly after, 9/9/2019 we will require the use of
rsconnect 0.8.15 or newer when interacting with shinyapps.io. Users of older versions, or of the long deprecated
shinyapps package, will receive an error message indicating that they must update.
Once TLSv1.0 and 1.1 are disabled on 10/15/2019, users of older versions of
rsconnect may experience protocol errors and not see the error message indicating the update is required.
