Hello Nicolai
I followed the description and created an additional clientservice. I now have the problem that the wrong HTML file is taken by the service when calling the address of the server and then the routing is incorrect and directs me to <gateway>/app/client/enaio/client
I could solve it by adapting the original index.html. For me the solution is ok but maybe others will face issues when more than one subdomain should work.
Regards Mathias
