message="To federate this app you need to add this line in your DNS configuration:

_matrix._tcp.$domain. 3600    IN      SRV     10 0 $synapse_tls_port $domain.

You also need to open the TCP port $synapse_tls_port on your ISP box if it's not automatically done.

Your synapse server also implements a turnserver (for VoIP), to have this fully functional please read the 'Turnserver' section in the README available here: https://github.com/YunoHost-Apps/synapse_ynh .

If you're facing an issue or want to improve this app, please open a new issue in this project: https://github.com/YunoHost-Apps/synapse_ynh"
