Welcome! :smiley:

We will need your actual domain name to diagnose this.

vpscozumel.com is the doomain name

So I did some checking. Your certificate issuance history through https://crt.sh/?q=vpscozumel.com looks like you’ve gotten a ton of valid certificates issued today for various domain/subdomain combinations. The certificate your website is actually serving for vpscozumel.com and www.vpscozumel.com has serial number 03b5925e6b6b442f9c09dbb5487d919a9d78, so those are working.

I think the problem is that you have included insecure content on your page. See https://www.missingpadlock.com and test your site to get more information. Your SSL is working, but you’re including content that is not delivered securely.

I only have 1 index page whit 1 img

Yep. And that one image is not included with https and thus is not secure. Just put an “s” after the http in your image tag and you’re good to go.

Tks friend working…

when ii trie to enter https://domaain.com:8443. not woorking or https://ip:8443

I’ve seen this somewhere before. Is the port really 8443 and not 443? I get great responses on vpscozumel.com:443 and www.vpscozumel.com:443.

Hi @martingbravo1

there are checks of your domain - see https://check-your-website.server-daten.de/?q=vpscozumel.com#ct-logs - last is some hours old:

You have created different certificates:

Issuer not before not after Domain names LE-Duplicate next LE
Let’s Encrypt Authority X3 2020-08-22 2020-11-20 *.vpscozumel.com, vpscozumel.com - 2 entries duplicate nr. 2
Let’s Encrypt Authority X3 2020-08-22 2020-11-20 *.vpscozumel.com, vpscozumel.com - 2 entries duplicate nr. 1
Let’s Encrypt Authority X3 2020-08-22 2020-11-20 vpscozumel.com - 1 entries duplicate nr. 1
Let’s Encrypt Authority X3 2020-08-22 2020-11-20 vpscozumel.com, webmail.vpscozumel.com, www.vpscozumel.com - 3 entries duplicate nr. 1

Your port 443 uses the wildcard, so non-www and www are secure.

Your port 8443 / Plesk uses the certificate with only one domain name:

CN=vpscozumel.com
	22.08.2020
	20.11.2020
expires in 89 days	vpscozumel.com - 1 entry

So your non-www port 8443 has a valid certificate, your www port 8443 not, there is your invalid certificate.

See the port check part:

www.vpscozumel.com
	8443
	Plesk Administration (https)
	open
	https://www.vpscozumel.com:8443/
Http-Status: 303
	Certificate is invalid Redirect: https://www.vpscozumel.com:8443/login.php?success_redirect_url=https%3A%2F%2Fwww.vpscozumel.com%3A8443%2F

Change that.

not woorking or https://ip:8443

A certificate with an ip as SAN is required. Letsencrypt doesn’t create such certificates.

PS: Your domain has a HSTS header. So you can’t create an exception in your browser to use www + 8443. Never add HSTS header if you don’t know if your certificate configuration is really working.
