Renovacion certificado

I had to renew the ssl certificate of uecrmv.edu.ec and it expired, then I renewed it, but so far it is not updated and I still get insecure

My domain is:

uecrmv.edu.ec

this comes out when using the sudo certbot certificates command:

Found the following certs:
Certificate Name: uecrmv.edu.ec
Domains: uecrmv.edu.ec *.uecrmv.edu.ec
Expiry Date: 2021-07-06 17:35:39+00:00 (VALID: 89 days)
Certificate Path: /etc/letsencrypt/live/uecrmv.edu.ec/fullchain.pem
Private Key Path: /etc/letsencrypt/live/uecrmv.edu.ec/privkey.pem

Please also include the answers the rest of the questionnaire:

I ran this command:

(I.e.: what command did you run to renew your certificate? And, if possible, what command did you use to get the certificate issued the first time?)

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

version
certbot 0.31.0
Distributor ID:Ubuntu
Description:Ubuntu 16.04.6 LTS
Release:16.04
Codename:xenial

command used:
certbot renew

This one is important too!

Do you know the command used to get the certificate for the first time, i.e., before certbot renew was possible?

Otherwise, please share the contents of /etc/letsencrypt/renewal/uecrmv.edu.ec.conf
