Problem with conference

Hi
i am having a problem with conferences.
i created a conference in free pbx and it asks for the pin number when i dial the number.

but it hangup the call saysing “that is not a valid conference number please try again” put the pin number is correct, when i enter a wrog pin number it says pin number is incorrect when is correct.

the problem is when i enter the correct pin it says “that is not a valid conference number please try again” i tried with admin pin and user pin both

my astrisk CLI is as bellow

Hi,

This may be a silly question, but does conference 4445 exist?

How are you getting to the conference, dialling an internal extension number or do you have something on an inbound route?

Thanks
