location / {
proxy_pass http://blogmenia;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/codepedia.info/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/codepedia.info/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot

if ($host = codepedia.info) {
return 301 https://$host$request_uri;

You can prepend a rewrite rule to your first server block like this
location / {
rewrite "/([0-9]{4})/([0-9]{2})/(.*)" /$3 permanent;
proxy_pass http://blogmenia;
}
This rule will permanently remove the date from your url it will look like this https://example.com/hello-world and then it serves the proxy
Note : you can update the regular expression in case of any date modifications in your url
