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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: mediajoy.info
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:
AWS
I can login to a root shell on my machine (yes or no, or I don’t know):
yes.
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 Spinupwp.com 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.
