License Error- Openflow

[satyajit_padhy]

I am exploring openflow from past couple of weeks. I tried to install openflow instance on the Linux server and after up the server i just check logs for the demo-api-1 containers and end up with the invalid license related issue. It would be great if you could assist.
Attaching screenshot for your reference.

Thanks in advance

remove the license key from the config, if you change the domain
