Internal Server Error 500 -- EC2, django, nginx, uwsgi - django

Question

I'm developing and deploying django based web-app through EC2 with nginx and uwsgi.
Because of developing Front-side (based on react), I send several http request to my server's public IPv4.
And the first few moment, my request is normally answered by server. All data is safely delivered to "http://localhost:3000".
But in some reason, after rebooting my EC2 instance, my nginx returned "500 (Internal Server Error)". More detailed information is descripted below.
[log]
/var/nginx/access.log --> any further information than internal server error

[What I tried after reboot server]
sudo systemctl restart nginx
sudo systemctl restart nginx.service
sudo systemctl restart uwsgi (my django server is automatically run server with this command)
sudo systemctl restart uwsgi.service
-> I check nginx and uwsgi is running safely. (with sudo systemctl status XXX command)
[What I tried differently to test server status]
postman request --> same result: 500 (Internal Server Error)
curl request inside EC2 instance terminal --> same result: 500 (Internal Server Error)
i expect to recover my server and know how to debug this error
