Hi Daniel,

Thanks for your clarification on below query!!

I have one more query regarding certificate , we have created new self-sign certificate and update in kamailio.
While checking syslog I found below logs, can you please clarify on this.
We verified file and location are same also permission also but still got below error.

Hello,

these messages can be printed when the remote party is closing the connection, it can be also a middle node like a home nat router.

Another case could be when the tls connection negotation fails, or that you should run kamailio with debug=3, but if it is a production system, then it might be too verbose. Maybe you can just increase the verbosity for tls module via debugger module.

Cheers,
Daniel
