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.
Also of note is ICANN Lookup shows Registry Expiration: 2025-06-03 17:37:42 UTC
and that is less than 90 days from now. I am not sure how that case is handled by Let’s Encrypt.
From your website https://leenkaz.com/contact-us/# I find +234 818 575 3131 for a telephone number; my quick research finds "234 is the country calling code assigned to Nigeria". Just trying to cut through language and cultural barriers in communications.
