django app static files on the different server not get loaded

[ningja]

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/?
