Hello, first thanks for the Manual of the Web App Gallery Setup, but in my case this dont work.

Following Situation, i have Setup a Web Server with the script ( Full WebServer without Database ) than i install the SQL Server 2014 ( Also with the Script )

I can connect to my Database when i test the Settings in the Web Server settings.

Now i follow your Manual to get the Web App Gallery to work.

When i have only the Mail feed URl with that enty it works but i see only some web Apps :

main Feed URL :  https://go.microsoft.com/?linkid=9842185

Here a screenshot with the Web Apps when i have only the main URL

When i add now the other Custom feeds, here a screenshot :

i get following screen when i click at teh web Server at the entry Web Application Entry :

The SolidCP event Log at the Web Server show me some entrys, all with the same contend :
