I cannot create a wildcard certificate because DNS API doesn't support it.
So, I have created a certificate for individual subdomains.

commands:
wo site update sub1.domain.com -le
wo site update sub2.domain.com -le

OS: Ubuntu 20.04.6
WordOps: v3.16.3
WAF: Sucuri (Only main domain).
All subdomains use the Sucuri DNS service only.

After creating the certificate when I opened sub2.domain.com it showed the sub1.domain.com certificate and got error Mismatch certificate error.

I check both subdomain's let'sencrypt "fullchain.pem" file and they are different and paths are properly set in ssl.conf for each subdomain.

Couldn't find out what causes this issue?
