Error #0349: you can't close the auto-created conference UID %d
 

Error description

Do not close an auto-created conferences on the client's side. You can only do it on Admin Panel by deleting the corresponding entry.

 
Problem solution

If you work with MyChat directly by using an official open protocol, check if you specify data correctly in the command.


Or, instead of client command, use a special administrative command from a protocol that contains all the necessary privileges.
