Question

How to get rid of "Server Certificate Verification Failed"?

So I was trying to add SSL to my site using this link https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04

But I messed up a few things as my SSL was successful but my site was showing an Nginx page rather than my site so I deleted and removed Nginx and Certbot. Now I am unable to install Nginx again due to “Server certificate verification failed”. Can someone one of you help me to resolve this issue?

Hi @littleturquoisesquid,

That’s quite weird. When you try and run:

  1. yum install nginx

or

  1. apt install nginx

You see the above error “Server certificate verification failed”, is that correct?

Additionally, what I’ll recommend is to only rework the nginx .conf of your app located in /etc/nginx/sites-enabled/nameof.conf

As for Certbot, if you’ve selected the option to do the redirect for you, you’ll be able to see a file called /etc/nginx/sites-enabled/nameof-ssl.conf. You can remove that one as well, you’ll be able to recreate it from Certbot afterwards.
