Facebook Dev: SSL and CURL error

Help
1

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. crt.sh | 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: tamango.cl

I ran this command:

It produced this output:

My web server is (include version): nginx 1.14

The operating system my web server runs on is (include version): Ubuntu 18.04

My hosting provider, if applicable, is: Digital Ocean

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 0.31.0

When I tested my site with SSLabs I got an A score: SSL Server Test: tamango.cl (Powered by Qualys SSL Labs)

However when testing with Facebook Developers I get the following errors:

SSL Error: Can't validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid.

Curl error: 60 (SSL_CACERT)

Hi @flizana

you have a www version, but the certificate of the www version is invalid.

I tried reinstalling the certificates, now running the command with both domains:

sudo certbot --nginx -d tamango.cl -d www.tamango.cl

But I'm still seeing the error in Facebook Developers console.

Reinstalling had worked, that's good. :+1:

What's the exact url Facebook uses?

Great, I think that was the issue then. The exact URL is https://tamango.cl

What Facebook tool are you using?

The debug tool shows it as fine: Sharing Debugger - Meta for Developers
