But port 80 is for HTTP not HTTPS, if I change the default server, I think letsdebug will display green
I'm afraid to change what works for everything spoiled my friends 
Finally, the curious side of developer took over, I have tests and I modified everything as it should be and there it is good... Everything is green
@Franck98 just so you know the certificate is only for apisnix-crm.com and not www.apisnix-crm.com
that should not be a problem if you never reference www.apisnix-crm.com

Thanks for the remark, but don't worry in the configuration of the domain name, I redirected www.apisnix-crm.com on apisnix-crm.com
By the way your capture, what did you consult the site with please?

I used SSL Checker - Check SSL Certificate to get the .PEM file for the domain
And then I take the .PEM file and use CSR Decoder and Certificate Decoder it to decode the Certificate. And then scroll down to the part I am interested in.
(I'm kind of lazy, all of this can be done with command line OpenSSL)

Actually, you don't redirect www to your apex. But, modern chromium browsers might. Some see that your cert only has your apex name (apisnix-crm.com) when you redirected http://www to httpS://www (emphasis on S is mine).
And, browsers work very hard to compensate for mis-coded servers and want to show something nice to their user. So, it redirects on your behalf (it's less efficient and some browsers might not). I don't know what browsers or versions support this but here's a message from the developer tool in Opera browser. See the "redirecting" message.
Curl is not as friendly. It fails your redirect
curl -I http://www.apisnix-crm.com
HTTP/1.1 302 Found
Date: Thu, 22 Sep 2022 02:06:24 GMT
Server: Apache
Location: https://www.apisnix-crm.com//
curl -I https://www.apisnix-crm.com
curl: (60) SSL: no alternative certificate subject name matches target host name 'www.apisnix-crm.com'
Also, note in the image above the message about the 404 Not Found error for that css.map file. There were several similar errors. I don't know if they are just missing or whether it is related to your two // in your redirect URL (after the .com). You might want to fix this at least for the performance improvement.

Oh, a recent Firefox version errors your www.apisnix-crm.com domain with a full screen "Security Warning".
It does not do the favorable redirect that chromium browsers do.
