Could you check through ssh if the Nginx process is running? I cannot find any log error, just the following:
2019/10/08 05:31:55 [error] 25700#0: *15139 client intended to send too large body: 4294967295 bytes, client: 184.108.40.206, server: localhost, request: "GET /msdn.cpp HTTP/1.1", host: "220.127.116.11"
Also, check if the ports are opened in the instance.
I guess that could be solved changing
client_max_body_size but not sure if that is related to your error.
i have created a new elastic ip 18.104.22.168 and https://www.wpscreators.com/
Could you clarify this? I can access that IP
