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.
Depends on how you installed the certificate in the first place. Unfortunately, you didn’t mention the client you’ve used and you haven’t mentioned the command you’ve used to install it, so for now it’s impossible to answer the question.
