My Peak Connection is currently open. How do I disconnect it? The limit has been reached, and I’m not sure which system I’m connected to. I need to disconnect it from all systems.

Hi @kyerwee

Welcome to Sendbird Community!

Please DM me about your application Id, and then I can investigate your current PCC.  
Also, you might refer to our guide about how we calculate PCC.  
[https://community.sendbird.com/t/usage-calculation-peak-concurrent-connections/2907](https://community.sendbird.com/t/usage-calculation-peak-concurrent-connections/2907)

To disconnect a user from our server, you should explicitly call the `disconnect()` function.
