I removed the ocserv.socket from the ocserv.service file completely and disabled ocserv.socket and it now works. Looks like a bug in ocserv from Ubuntu repository. I?ll try to install on Debian 9 later to confirm that I do not need this workaround. The ocserv version from Debian repository seem to be different.
