Git Pull Issue

Hi team,

When I trying to push some code to bitbuket, it returns ssl error, do you have any idea about how to fix that?
git -c diff.mnemonicprefix=false -c core.quotepath=false fetch origin

git -c diff.mnemonicprefix=false -c core.quotepath=false pull origin master
fatal: unable to access 'https://kavipokhariya@bitbucket.org/webmasterpcj/demopcj.git/': Unknown SSL protocol error in connection to bitbucket.org:443

Completed with errors, see above.

Thanks,
Kavi
