Is there any way I can use Jitsi with LetsEncrypt on Ubuntu with the Android client?

Heya,

Just came across this answer and decided to write some general guidelines for anyone who comes across this in the future despite the old question.

Looking into this Jitsi community recommends checking a few things:

1. Certificates: Ensure that Let’s Encrypt SSL certificates have been correctly installed and that all relevant ports are open on your droplet.
2. Ports: Ports 80, 443, 4443, 10000-20000 should be open.
3. NAT configuration: If your Jitsi server is behind a NAT, you need to ensure that the NAT is properly configured.

For any changes in the configuration, make sure to restart Jitsi services using systemctl restart jicofo jitsi-videobridge2 prosody to apply those changes.

Please note that the procedure can vary based on the configurations and settings of your server. You might find this DigitalOcean document on Configuring a Firewall useful.

Hope that this helps!
