When you hate to see your website has ssl invalid certificate and it crossed out like this:
That means you need to update ssl certificate, in this case I use let’s encrypt. I just want to get rid of the invalid ssl certificate logo that make your website looks very unprofessional 🙂
Navigate to path where you place let’s encrypt directory:
$ cd ~/letsencrypt ~/letsencrypt$ sudo ./certbot-auto renew
Finally, restart the nginx, This is using centos, so it’s gonna be like this:
$ sudo /etc/init.d/nginx restart
Done
