Hi @nzqadri which warning, about the license? In that case you have to check the /etc/ntopng.license file if it's empty, in case you have to add the license in that file and restart ntopng. You can follow this guide to recover the license: https://www.ntop.org/faq/how-to-recover-issued-licenses/

Basically I was using 18.04 and upgrade to 20.04 OS using free version which automatically licensed somehow but here it's not working.
