LetsEncrypt - SSL certificate is not valid

Well, if everything is ok... it should work..

BTW, the error reported by certbot, has nothing to do with certbot itself

Quote from Nuxwin

Good morning

So many solutions here

The problem is not about certbot, nor about i-MSCP or its LetsEncrypt plugin but about openSSL v1.0.x which cannot validate the SSL certificates.

To solve the problem, you need in order:

1. Make sure that the CA ISRG Root X1 is installed on your system (in /etc/ssl/certs) : PEM AVAILABLE HERE
2. Remove the old X3 (mozilla) CA which has expired

kess Good job. I don't think that all steps are required. You don't need to import the full CA. Regarding certbot, I'll update it.

kivamp You're totally right. To solve the problem, install the ISRG root X1 and remove the expired one manually from /etc/ssl/certs

There is nothing running on your port 443, did you installed the plugin correctly and enabled a certificate for this domain?

Are you the server administrator and using i-MSCP at all? The Letsencrypt Plugin from this site is specifically for the hosting panel i-MSCP.

Also you should open a new thread, and not hijacking anothere one, where the issue is totally different.
