Messaging for In-App and Web, getting error in Digital experience site.

I was configuring messaging for web for my digital experience site in scratch org with routing type (queue/flow). I setup everything as per salesforce help page. 

After publishing the experience site, it won't show component on page.

In console, it shows this error,  "Unable to load Embedded Messaging configuration". 

I have added CORS, Trusted sites. I retested the setup. I have tried to show messaging component on VF page too but component is not visible.

am I missing something? please help.

Thanks in advanced.
