Yes actually. I have experienced this problem before myself. It is an issue with the plugin and your firebase credentials. The most common case is the SHA-1, that you must provide to setup on Android is not set as it should be.

Please review https://github.com/EddyVerbruggen/cordova-plugin-googleplus/issues/243 for a possible solution.
