Hi everyone, I try to implement an External Portal Server for Authentication. I am using Nginx and Django to run a Log-in page.

I'm struggling with the get portal page step (which is step no. 5 and 6 in this link  https://www.tp-link.com/th/support/faq/3231/ ) 

The problem is when omada controller redirect the client to portal page with all parameter, client could not receive a second GET request from Nginx and Django (static file in Django eg. image, CSS). Omada Controller allows only first request which is made after omada controller sent redirect to client and blocks all other GET request.

Does anyone has this experience? 

Here is log from Nginx when I test in local pc:
