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.
It looks to me like you’re a customer of the hosting provider 247workinghost, and they don’t want you to get certificates for subdomains of their domain. If so, that’s their choice.
Do you have your own domain name that you’ve registered for yourself? If not, and if you don’t intend to do this for some reason, you’ll need to ask 247workinghost whether it’s OK with them for you to get a certificate for this subdomain, and, if so, whether they can help you do so. It’s very unlikely that we can help you to do this without their cooperation!
I am from 247workinghost.com and i want this certificate for my hostname, which is mentioned above as sub domain name. I want to renew it for myself and i have main administrative access to the server. Waiting for your help to re-generate it.
To use Let’s Encrypt, you have to add a CAA record for 0 issue "letsencrypt.org" to 247workinghost.com or win02.247workinghost.com or remove the existing CAA record.
Do you have administrative access to the domain’s DNS?
Yes i have access, do i have to delete the entry of old/existing certificate from the DNS records and need to re-issue ? Is it right or what to do, please mention step by step guide.
