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.
Unless the private key was lossed on e.g. an USB-stick which was stolen/left in the pub/public transit et c. (i.e.: leaked), there's no reason to revoke.
