I have two server test1.com and test2.com. test1 is internet public face server. Test2 is intranet only server. Both servers have nginx docker running.
Test1 run a Django app1 which has static files under /app/public/static. App1 can load the static files and run correctly from URL https://test1.com/app1. Test2 has a Django app2 which has static files under /app/public/static on server test2. From URL https://test2.com/app2. Every thing works include static files.
The issue is I need config nginx1 to allow people to access app2 from internet.(public)

With the configuration nginx1 blow I can load the app2 but not the app2 static files. The error is :
"GET /static/img/logo-2.jpg HTTP/1.1", host: "test1.com", referrer: https://test1.com/app2/ . The nginx is looking for app2 static file under test1 which obviously ‘file not found’.
How can config nginx1 to looking for app2 static file under test2.com https://test2.com/app2/?
