Issues: "Useless certificates" & "Intermediate certificate is not provided"?

[ozgurkazancci]

Hi.

On my OpenBSD server, I used to use acme.sh for having SSL certificates, recently I switched to lego and it seems better and fine, however I'm having an issue that I had no such thing with acme.sh, so here it goes;

When I check my SSL health through: https://www.immuniweb.com/ssl/ - I always get two different warning messages.

1- Creating my certs by using lego without: --no-bundle;

lego -a -m info@mysite.com -d mail.mysite.com --http --http.webroot /var/www/lets --path /etc/ssl/domains/ --pem run

And after checking my server, the website says; "Server sends useless certificates." See please: https://i.ibb.co/nbprk4L/lego-2.png

2- Creating my certs by using lego with: --no-bundle;

lego -a -m info@mysite.com -d mail.mysite.com --http --http.webroot /var/www/lets --path /etc/ssl/domains/ --pem run --no-bundle

Then, the website says; "Intermediate certificate is not provided by the server." See please: https://i.ibb.co/gTZMrsV/lego-1.png

My nginx block has;

ssl_certificate /etc/ssl/domains/certificates/mysite.com.crt;
ssl_certificate_key /etc/ssl/domains/certificates/mysite.com.key;
ssl_trusted_certificate /etc/ssl/domains/certificates/mysite.com.issuer.crt;

Am I doing something wrong?
