Since some versions we have a problem with the Universal GUI after updating. The setting "requestFiltering removeServerHeader = true" in the web.config file causes a 500.19 HTTP error when starting the Universal GUI.
If we remove the lines below from web.config, the problem is gone.

       <requestFiltering removeServerHeader = "true" />


The problem is also present with the most recent update.

Hi Marc,

In IIS 10.0 the attribute has been added. Are you using IIS 10.0 or above? If not, you should upgrade to it to be able to use this attribute.


Kind regards,

Okay Mark. Thanks for clearing this up. At the moment we’re not using IIS version 10.0, so that's causing our problem.
