As soon as I start Rhostudio I get an error like:

PWD: d:\RhoMobileSuite5.1.1\ruby\lib\ruby\gems\1.9.1\gems\rhodes-5.1.1
CMD: rake token:check

>>>> A cacert.pem bundle could not be downloaded.
-$TIME$- message [ First timestamp ] time is { 2016-09-30T04:41:40Z } milliseconds from start (0)
getting cert bundle
RET: 1

This occurs in RMS 5.1.1 and RMS 5.5 (Open Source)

Any solution?
