Unable to access Qlik Sense Hub and QMC using DNS alias: The target name used is not valid


Unable to access Qlik Sense Hub and QMC using DNS alias: The target name used is not valid

Accessing Qlik Sense with DNS alias name fails when accessing within the server where Qlik Sense is installed. However, it works when accessed by a client machine outside the Qlik Sense server where it is installed.

We see below warning in Windows System Event Viewer logs,

The program Proxy.exe, with the assigned process ID 9928, could not authenticate locally by using the target name HTTP/qliksense.SERVERNAME.com The target name used is not valid. A target name should refer to one of the local computer names, for example, the DNS host name.

Try a different target name.
