Chrome v96 does not allow microphone and camera access to talk due to HTTPS (https is installed)

Since I updated Chrome, I cannot access to Talk meetings. Actually I have a Nextcloud instance installed with Docker, reachable with a nginx proxy. In a second machine, I have an High Performance Backend reachable using another Nginx proxy. Both proxies have a letsencrypt valid certificate.
The error I get is: Access to Microphone and Camera is only possible with https, please move your setup to HTTPS.

Of course I have only HTTPS connections.
Other browsers, like firefox are still working
