Ssl install problem on AWS ec2 instance

Thank you so much for the great support and wonderful product. I have been using it for the past 1 month and just simply love it. Excellent product and support !!!
I have installed webODM on aws ec2 instance and followed the instruction as per

and all worked fine. After that I restarted with ssl using my ec2 instance IP.
./ restart --ssl --hostname (my ec2 instanceIP)

But I got this error !!! Should I use a registered sub-domain or Elastic IP?

Hi there, I’m with the same problem. Did you solved it? Cheers

IP is not an hostname. You cannot use an IP address; you first need to register/setup a DNS A record (e.g., then pass the domain name in the hostname parameter.
