Errors with SonarLint new eclipse workspace

I am having issues when running SonarLint with Eclipse.
SonarLint 4.1.0
SonarQube 6.7.4

The bindings and the connection works fine in Eclipse initially but when I create a new eclipse workspace and import the same source code as in the old workspace, I start getting these errors:

Project “project name” is bound to an unknown server: ‘server url’. Please fix project binding or unbind project.

The bindings file org.sonarlint.eclipse.core.prefs was available in the new workspace. Errors went away when I did the same bindings again.

Does SonarLint store this binding information other than the prefs file ? Is it stored in the eclipse workspace as well ?
