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: 220.127.116.11, server: localhost, request: "GET /msdn.cpp HTTP/1.1", host: "18.104.22.168"
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 22.214.171.124 and https://www.wpscreators.com/
Could you clarify this? I can access that IP
