STUN/TURN when nextcloudTalk is on same server

I want to install Jitsi on a Ubuntu 18.04 VPS, according to this guide: Self-Hosting Guide - Debian/Ubuntu server · Jitsi Meet Handbook

My problem is: On that server, there is already a nextcloud server, including nextcloudTalk and therefor a stun/turn server “coturn” is already installed and in use.

My question is: Can jitsi use that very same “coturn” instance for the STUN/TURN functionality? Or is it possible to run TWO instances of “coturn” service (on different ports, once for nextcloudTalk, once for Jitsi)?

I am using Apache, not nginx. And I don’t use any docker.

You should be able to use the same coturn server.
