The Domain Mapping Plugin is not working on our multisite

Hi,

The domain mapping plugin does not seem to be working on our multisite. We currently have a subsite- http://wordpressmu-2651-6193-33157.cloudwaysapps.com/egenetics, which we are attempting to map to the domain- http://egenetics.eu.

Unfortunately the plugin does not seem to be working. Please see screenshots for further clarification.

Thanks,
Mark
