Since a few weeks, I\'m not able to pull or push from or to the remote repository. I thought it happend when upgrading to IntelliJ IDEA 14, but I can reproduce the problem w
Go to Preferences > Version Control > Git. Make sure SSH executable is set to “Native.” (If it's already so, switch it to “Built-in,” apply it, and then again switch back to “Native.”).
If this doesn't solve your issue, I would suggest to download a Git client such as GitHub client (free desktop app) and try to sync your project through the app. Then go back to IntelliJ and check if it works.
