The error:

Authentication error has occurred

Is probably because of VNC's TLS encryption that is not always supported by remote clients.

Solutions ...

Recommended

Use a remote desktop client/app that supports TLS encryption.

Not recommended

This was an issue with the older Ubuntu releases when connecting from Windows remote desktop app and a workaround was to disable encryption with:

gsettings set org.gnome.Vino require-encryption false

In newer releases, however, the only possible way to do that is to disable encryption in the default key-ring by setting a blank password for the key-ring authentication ... This however brings with it some serious security hazards so, be careful.
