Matrix RTC not available

[sandmaennchen5]

Matrix Server:

• Host: VPS
• fix ipv4 + ipv6
• OS: Ubuntu 24.03
• Architecture amd64
• Ansible latest Dockerimage

New Server runs perfectly with bridges and federation.

Have installed RTC with matrix_rtc_enabled: true

Server is configured with nothing special accessible with A and AAAA DNS via matrix.domain.de

In the base domain I copied the created well-know from the Playbook from Trafix folder and placed it in the base and also set the SRVDNS _matrix._tcp

Well-know
