Unit jitsi-videobridge.service not found

I rebooted my Ubuntu 18.04 server and seems like Jitsi did not auto-start correctly so I’m trying to reload videobridge but I’m getting the following error::

COMMAND:
systemctl restart jitsi-videobridge

ERROR:
Failed to restart jitsi-videobridge.service: Unit jitsi-videobridge.service not found.

Please can you tell me how to reload all Jitsi services.

EDIT:

I have followed this guide: https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md
It was working fine for a couple of weeks now but the issue appeared only when I rebooted my server.

Thank you

systemctl restart jitsi-videobridge2

Works like charm. Thank you @Supun_Madushanka
