download data from https://rubygems.org/ - SSl_connects returned=1

I am trying to install sass and I tried ruby installer. I am getting the error as follow.Please anyone help.

gem install by default uses https://rubygems.org/ as it's source for gems, but you can specify the source using --source option and give a non-SSL source to install like following:
gem install sass --source http://rubygems.org/
I am trying to install a migration tool called move to go for a CRM system called Lime but I get an error. I dont know why, the certificate says it's valid in the SSL.

Any suggestions?
This is due to Ruby SSL certificate that has changed.
You can install a newer version of RubyGem to fix the issue.
Example, on Windows:
Download https://rubygems.org/downloads/rubygems-update-2.6.7.gem and save it to C:\rubygems-update-2.6.7.gem
Open a command prompt and run the commands :
gem install --local C:\rubygems-update-2.6.7.gem
update_rubygems --no-ri --no-rdoc
gem --version and check it is 2.6.7
gem uninstall rubygems-update -x to remove the update package
Finally, retry your gem install command and the SSL error should be gone !
