Getting ERR_CERT_AUTHORITY_INVALID error

Hi, I’m trying to install and connect to my Misskey instance and I’m facing an ERR_CERT_AUTHORITY_INVALID error. I tried following the instructions in this link (https://www.digitalocean.com/community/questions/getting-err_cert_authority_invalid-error) but it didn’t work. I used the certificate and key provided by Cloudflare. The path of certificate is correct, I restarted nginx, but why doesn’t it work? Any answers would be appreciated. I am attaching a picture for your quick understanding.

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name anarkia.dev;

    ssl_session_timeout 1d;
    ssl_session_cache shared:ssl_session_cache:10m;
    ssl_session_tickets off;

    # To use Let's Encrypt certificate
    ssl_certificate     /etc/ssl/certs/cert.pem;
    ssl_certificate_key /etc/ssl/certs/cert.key;

    # To use Debian/Ubuntu's self-signed certificate (For testing or before issuing a certificat>
    #ssl_certificate     /etc/ssl/certs/ssl-cert-snakeoil.pem;
    #ssl_certificate_key /etc/ssl/private/ssl-cert-snakeoil.key;

Heya @44a03fe70a384a7ca7abc3b64e2e72,

The error message you’re encountering, NET::ERR_CERT_AUTHORITY_INVALID, indicates that there might be an issue with the SSL certificate or its configuration. This error is not because you’re using a free Let’s Encrypt SSL certificate, as they are trusted by most modern browsers.

Here are a few things that I could suggest:

Check the SSL certificate and key paths to ensure they are correct and the files exist:

ls -lah /etc/letsencrypt/live/domain/fullchain.pem
ls -lah /etc/letsencrypt/live/domain/privkey.pem

Restart Nginx after making any changes to the configuration file:

sudo systemctl restart nginx

Ensure that your domain’s DNS settings are correctly pointing to your DigitalOcean droplet’s IP address. You can use this tool to check that:

If the issue persists, you may want to consider reissuing the SSL certificate using Certbot or checking the Certbot logs for any errors. You can do that by running the certbot command again.

Let me know how it goes!
