As I cannot find answers on the web, I seeking for help here. Sorry for my bad English.
I have a SharePoint 2013 on premise with SSL apps fully working in my company network. The SharePoint web application are published on internet and they work well too except for apps access.
Ok, lets say my domain is
contoso.com and my apps domain is
I've publish my web application URL
https://project.contoso.com but how can I publish my app domain?
In my understanding it's not possible to publish a wildcard URL like
*.contosoapp.com on the web. This is what we do on our internal DNS, but how to do that over the web?
So am I missing some SharePoint or DNS configuration? AS every apps URL will be different how can I do?
