Qlik Sense was configured with SameSite attributes such as:
<add key="SessionCookieSettings.Https.HasSecureAttribute" value="true"/>
<add key="SessionCookieSettings.Https.SameSiteAttribute" value="None"/>
The settings were applied to Proxy.exe.config file, which by default is located in "C:\Program Files\Qlik\Sense\Proxy".
After an upgrade, the implementation (mashups, iframes) stopped working.
Environment
Resolution
Beginning with April 2020, Qlik Sense allows for configuration of SameSite attributes directly in the graphical userinterface. Changes applied to the proxy.exe.config file will be ignored.
See Qlik Sense: Missing SameSite attribute now blocks requests in Chrome 80 and future browsers for details on how to configure the settings.
