Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
The Letsencrypt certificate is created from your cPanel and has all domain names. The newer Sectigo certificate is wrong, mykidmall.com is missing. So you shouldn't use that certificate.
The “expiry in 81 days” part is perfectly normal; certificates from Let’s Encrypt are good for 90 days. If the Cpanel integration is working as it should be, the certificate is automatically renewed before it expires (usually about a month before it expires).
Thanks for reply and your professional support. May i know what should i do next to solve this issue? I am a layman on this SSL.
Should i purchase another SSL certificate or is there other way to re-do the SSL?
I need your professional advise.
