I created the Client ID on Google side, set to true the line 294 on
/etc/jitsi/meet/example.com-config.js and finally add the
googleApiApplicationClientID line with the ID.
I know that because I wrote all step by step. The doc it’s a little tricky.
If you made some change in the other *-config.js, try to reverse it.
Finally I made a reboot to be sure that all the services will take the new changes. I know that restarting the services should be enough. But I saw that sometimes with Jitsi is better a reboot.
When I stuck like you, I tried to start over from scratch.
- Reverse all changes made regarding this (Calendar in this case)
- Create a new app and ID on Google side
- And uncomment the lines adding the new values (ID)
You will never know if you made a simple mistake that is blocking your current goal.
