Failed to load Jitsi Videobridge

Hello,
After a succes manual installation of jitsi meet (it worked), I tried to do the same with Ansible but during the process I face a problem when i did:
- name: restart service videobridge
service:
name: jitsi-videobridge
state: restarted
After that It’s been impossible to restart jitsi-videobridge service. I try to remove and purge the package to finally reinstall it but it didn’t works.
here is an extract of the logs of jvb.log:

thanks for your help

This error seems to be solved after killing the process (ps -aux | grep jitsi-videobridge then kill ), remove the file “/var/run/jitsi-videobridge.pid” and restarting the installation of jitsi-videobridge.
