After adding guest.domain.com starts showing error - Bridge Channel send: no opened channel

Installed jitsi on Aws 18.04 debian OS with nginx server. Everything working fine till I add the domain - guest.domain.com. If I keep the authentication enabled for all users i.e without guest it is working fine. Is it because there is no ssl certificate for guest.domain.com?
Getting error in console as - Bridge Channel send: no opened channel.
