Nginx - redirected you too many times

Hi, I'm using Ubuntu 18.04 LTS and I setup LEMP stack using Webinoly. I uploaded an existing wordpress website and enabled SSL using site domain.com -ssl-on. But I'm getting the error "domain.com redirected you too many times." Here's my nginx configuration.

    server {
            listen 80;
            listen [::]:80;
            server_name iflytravelsolutionsinc.com www.iflytravelsolutionsinc.com;
            return 301 https://$host$request_uri;
    }

    server {
            listen 443 ssl http2 default_server;
            listen [::]:443 ssl http2 default_server;

            server_name iflytravelsolutionsinc.com www.iflytravelsolutionsinc.com;

            # WebinolySSLstart
            ssl_certificate /etc/letsencrypt/live/iflytravelsolutionsinc.com/fullchain.pem;
            ssl_certificate_key /etc/letsencrypt/live/iflytravelsolutionsinc.com/privkey.pem;
            ssl_stapling on;
            ssl_stapling_verify on;
            ssl_trusted_certificate /etc/letsencrypt/live/iflytravelsolutionsinc.com/chain.pem;
            # WebinolySSLend
