Dear @Josue ,
I have changed Internet access provider, and I try to set up correctly port forwarding, that’s why my previous questions.
So my public IP address has changed also.
Messages through Matrix works well again.
But I tested again Element X calls and it doesn’t work anymore. Call ring on the other phone, I can answer, but the media can not be shared and the call end before I can talk (“unexpected error occurred (Error Code: Unkwown_Error)”). The same from within the same network, or connected to external IP (through 4G).
I have updated coturn IP address in /etc/matrix-synapse/coturn.conf but I understood it is useless for Element Call, no?
Is there anything else I should update to make it work in my new setting?
