i’am new to jitsi and i installed it using command lines .
i configured the config.js file under /etc//jitsi/meet
dropbox: {
appKey: ‘tm75zl19pcgjth4’
},
and when i enter my dropbox credentials an error with “Recording failed to start” appears

Check your jibri logs, did it fail or is it connected to your deployment?

i have jibri installed and after executing ls /var/log/jitsi/ →
jicofo.log jvb.log
