Hi,
I just installed the latest RC (2.6.0-rc.3). I can confirm this.
It looks like the bbb-install script deleted my monitoring.nginx file in /usr/share/bigbluebutton/nginx. I just had to recreate it.
However, I'm getting an error in the bbb-exporter container regarding recordings.
I'm currently looking into it. Will post if I find something.
Regards,
J.
