Hello,
I’m experiencing the same issue on both versions 15.1 and 15.2. I lose the connection, and during this period, users attempting to register encounter an error and the log is displaying “Attendee limit reached.” Once I reconnect my own application, the problem is resolved, but only for around 24 hours.
PHP Version: 8.1.23
WordPress Version: 6.4.3
Plugin Version: 15.1 & 15.2
Application Used: Own Application
