error setting certificate verify locations: CAfile ca-bundle.crt CApath: none

I am trying to install the plugins directly from wordpress admin panel (instead of manual download and install). I am getting this error

Downloading install package from http://ift.tt/1QujitD

Download failed. error setting certificate verify locations: CAfile: /home/xyz/
public_html/http://ift.tt/1TTTGUR CApath: none

1. I checked the certificate. Its working fine. Even i replaced it with fresh copy. Still I am getting the error.
2. I deactivated other plugins.
3. I checked for file permissions. Its also ok. (Files - 644 and Folder - 755)
4. I contacted hosting support. They searched and tried to solve the issue but they said its not issue on their end.

I am unable to get the root cause. Please provide the solution. Any help would be appreciated.

Thank you, Mahesh
