As a part of code, if the serverAddress unavailable or user could not be connecting from the IPs specified in clientSource . Can you please check the serverAddress is valid and please share complete error log along with the bindIp specified in your deployment.
Thanks Darshan, Does bindip mentioned 0.0.0.0 in config file can be the reason of this error?think I found the cause, router is listening to 127.0.0.1 and we are restricting to internal ip, we must add that ip also listening right?
