Hi everyone, i might have messed up my configuration and im not able to renew the certificate, any idea how to fix this ?

Hi @crashbdx

your configuration isn't good, but certificate creation should work ( https://check-your-website.server-daten.de/?q=sica-web.app ):

Port 80 is open, checking /.well-known/acme-challenge/random-filename there is the expected result http status 404 - Not Found.

You have a

Server: nginx/1.14.0 (Ubuntu)

so check your port 80 vHost to find your root, then use it:

certbot run -a webroot -i nginx -w yourRoot -d sica-web.app -d www.sica-web.app

Perhaps update your Certbot, 0.23 is very old.

I tried the following:

certbot run -a webroot -i nginx -w /home/sites/webapp -d sica-web.app -d www.sica-web.app

But getting this:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
The requested nginx plugin does not appear to be installed

As im not really sure what i done and the version seem outdated, is there a simple way to just remove everything and redo a clean install and generate a new certificate? or do i have to do that after the current one expired?

You have to update your certbot.

0.23 is too old, if nginx isn’t supported.

Or you try to use certonly, so you have to install the certificate manual.

But I don’t think you want to do that every 60 - 85 days.

Or switch to certbot-auto. Your Ubuntu should be ok.

I updated certbot to 0.31.0 then just did:

sudo certbot --nginx -d sica-web.app -d www.sica-web.app

and got:

Your existing certificate has been successfully renewed, and the new certificate
has been installed.

The new certificate covers the following domains: https://sica-web.app and
https://www.sica-web.app

You should test your configuration at:
https://www.ssllabs.com/ssltest/analyze.html?d=sica-web.app
https://www.ssllabs.com/ssltest/analyze.html?d=www.sica-web.app

Now valid untill: Sun, 04 Aug 2019 13:34:15 UTC (expires in 2 months and 28 days)

Thing is i use certbot-auto on another server, i probably should switch to it on this one too, do i just uninstall certbot and install certbot-auto or there might be conflicts?

Thanks a lot for all the help, saved my day :slight_smile:
