Let's Encrypt certificate insecure by web browser

My domain is: https://www.aulasprofdanilo.com.br/moodle/

My web server is: Apache2

The operating system my web server runs on is: Ubuntu Server 18.04 LTS

When I access my web page by any different web browsers it returns that it is not secure. I have already checked my certificate and it’s okay. My SSL test can be viewed in: https://www.ssllabs.com/ssltest/analyze.html?d=www.aulasprofdanilo.com.br.

Please, what is the problem with my certificate?

The certificate looked pretty normal…

My bet is on your browser cache… Can you try to view it again now?

Thank you

After the site loaded it continued with a tls handshake with… for almost 20 seconds. The site did load and appears to be okay. The LE certificate is okay.

Hi @danilo_m

there is a check of your domain, ~~6 hours old - https://check-your-website.server-daten.de/?q=aulasprofdanilo.com.br%2Fmoodle%2F

http has a timeout. That may be a problem if users don’t add https. And there is a small content problem you should fix (wrong inline images), but that’s not a certificate problem.

Hi, @JuergenAuer!

Thank you to the answer. Yes, I have accessed recently this web site to verify my domain, but I did not understand what I should do. Can you help me?

Hi, @JimPas

Thank you to the answer. I’m going to look to it!

Yes! I think that certificate and web site it is okay! But certificate error message continue.

Honestly, I do not know what to do anymore.

But that’s

your domain.

What url do you use?

I use both URLs. Do you think that when I created my Let’s encrypt certificate needed to be different?

There are more 6 images but appear a message (rule of the forum) that limit my images atachs to 1 (new users).

That’s not required. But you shouldn’t see any error.

Url used -> domain name is in the certificate -> no error.

So I don’t understand why you see that error.

Perhaps use Chrome, then Ctrl + Shift + I, then check Security.

It will not work if you use a raw ip address.

(do you see what happens when you hide details from us?)





a waste of our time.

You don’t use your correct url.

PS: And your ip address is public, that’s how the internet works.

Yes! I don’t understand too. But I’m going to do what you’ve asked me at Chrome.

Thank you!

This information that I’ve omitted is my IP server. ( 192.168…)!

Okay, thank you. What is the correct so?

Appear that in Chrome security:

If you use your ip, that can’t work. Your certificate doesn’t include an ip address. And can’t, because the ip address is private.
