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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: Host-It
I can login to a root shell on my machine (yes or no, or I don't know): I don't know
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Plesk
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
I simply entered a defunct email by mistake when installing the certificate. [redacted] no longer works and should be [redacted2]. How can I correct the mistake, please
The ACME protocol allows you to update the email address. Usually you'd use the ACME client used to get the initial certificate.
Looking at the few answers we got on the questionnaire, I'm guessing you've used Plesk to get the certificate to begin with? Proooobably using the SSL It! Plesk Extension.
Unfortunately I don't easily see a way to update the email address from the Plesk documentation. Maybe someone of the Plesk Community knows how to do this. Or one of my fellow volunteers here if you're lucky.
Thank you. I am using Plesk. Can I cancel the certificate and start again from scratch ? If so How do I cancel ? The website is not being used at the moment.
I have no idea if that will update the email address, sorry. Maybe it does, maybe it doesn't.
In the end, the email address is "only" used for expiry reminders (which you shouldn't get to begin with if automated renewals all work out) or important changes in the service (which are probably not as important to regular end users compared to e.g. hosting providers or ACME client developers).
I'd recommend searching or opening a thread on the Plesk support channels.
