ntopng https web server does not present full certificate chain
The https protected web frontend (port 3000) of ntopng 0.8.13_6 (tested on pfSense CE 2.4.5_1) does not work correctly with certificates which have a longer CA certificate chain than 1.
The https web server seems to use the same certificate as the web configurator frontend. It does not send the intermediate CA certificates in the https handshake, though. This results in a certificate error on the relying party (web browser) because the certificate chain of the EE certificate cannot be validated.
Suggested solution: build the certificate chain of the web server certificate. Send all certificates of the certificate chain, excluding the Root CA certificate.
