Warring (error message) in browsers when accessing Qlik Sense HUB or QMC
Ex: your connection is not private, this site is not secure, this is not secure, ...Environement:
Qlik Sense All versions
This message is a warning made by Windows/browsers, to say that the SSL Certificate used to encrypt the communication between the browser and Qlik Sense isn't trusted by the by the OS maker (Microsoft, Apple, Redhat....), which doesn't mean the communication won't be encrypted.
This can be cause by many certificates issues and mismatch but doesn't prevent the user to access the page (unless stated otherwise by a domain policy)
In many cases you can find out what is the "issue" with the error message in Chrome:
NET::ERR_CERT_COMMON_NAME_INVALID: this is usually due to a mismatch between the site name and the site or domain the certificates has bee issued for
NET::ERR_CERT_AUTHORITY_INVALID: this is usually due to that the authority that has issued the certificate isn't recognised Usually because the certificat is a self-signed and hasn't ben bought in a recognised (verysign, godaddy, digicert,...) by the OS maker (Microsoft, Apple, Redhat....).
in this case you can ask your domain admin to add it in the Trusted Root Certification Authorities of the domaine and have it distributed to the computers of the domain. Note that computer external to the domain will still have the warning
