Moving Certificate To Another AWS Server

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

My web server is (include version):
Ubuntu 18.4
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 installed via shell an SSL certificate for my domain (wordpress on my EC2 AIM)and it worked great.
But my server code broke so I had to reinstall a fresh copy of my wordpress site on another AWS server.
I had install a Certbot (for Let’s Encrypt TLS/SSL certificates) for me for the same domain.
Now I got the message CA not valid. See attachement screenshot.

Hi @mediajoyinc

checking your domain with my FireFox, all works.

Ah - there is a problem - checking your domain via

Domainname Http-Status redirect Sec. G 301 Html is minified: 109,46 % 0.233 A -8 0.453 W

Your non-www works, your www not. Both www versions don't work (http and https).

If that's the problem:

  • Fix your http.
  • Then create one certificate with both domain names

Now your certificate
expires in 90 days - 1 entry

has only one domain name. But

Issuer not before not after Domain names LE-Duplicate next LE
Let's Encrypt Authority X3 2019-11-14 2020-02-12 - 1 entries duplicate nr. 1
Let's Encrypt Authority X3 2019-11-08 2020-02-06, - 2 entries duplicate nr. 1

you have already created a certificate with both domain names, so you can re-use that certificate.

Yes. Every Letsencrypt certificate is only 90 days valid.
