I have a domain tinericms.com which has wildcard certificates enabled. The letsencrypt account was created by my predecessor using his email address. Hence i tried to change the registration email of the account a few months back using the following command
sudo certbot register --update-registration --email firstname.lastname@example.org
It gave me a successful response. But now less than 20 days are left and i have not recieved any warning email on my email account and i cannot check with my predecessor because his email id has been disabled. Please can anyone help me.
I have attached the regr.json file. It shows the changed email but not recieving any alerts on it.
