Hi @ramya
there is a check of your domain, ~~50 minutes old - iravelshop.com - Make your website better - DNS, redirects, mixed content, certificates
You have created the correct certificate:
| Issuer | not before | not after | Domain names | LE-Duplicate | next LE |
|---|---|---|---|---|---|
| Let's Encrypt Authority X3 | 2020-02-03 | 2020-05-03 | iravelshop.com, www.iravelshop.com - 2 entries | duplicate nr. 1 | |
| Let's Encrypt Authority X3 | 2020-02-03 | 2020-05-03 | iravelshop.com - 1 entries | duplicate nr. 1 |
But you don't use the certificate with two domain names. Instead, the certificate with one domain name is used.
certonly doesn't change your configuration, so you have to do that manual.
There is an Apache, what says
apachectl -S
certbot-auto certificates
Find your correct port 443 vHost with both domain names, then change the certificate files.
