Jibri recording didnt start

i have 2 server one is for jitsi another for jibri with docker,when i start recording it shows recording failed.
in jicofo.log it shows error
WARNING: [249] JibriIqHandler.handleRequest#65: Jibri IQ not accepted by any conference:

Did you configure Jibri with proper credentials to connect to Prosody?

yeah its configured properly with prosody…do u need any configuration file i can share.

Check the jicofo and jibri logs to see if jibri joined the brewery.

issue has been resolved,there is some problem in lets encrypt certificate,after adding a paid ssl its worked.
