I host several websites with my hosting provider. I have successfully installed several certificates for the domains hosted there. When I tried for the domain tugelarapids.co.za I got this message:
“Error creating new registration.Type: urn:acme:error:invalidEmail”
Strange. So I tried again and again
I eventually used my gmail address, and then it worked.
Is there a limit to the number of certificates lets encrypt will generate for a single email address?
I am using plesk control panel …
An example domain I installed a certificate using my email address : cavern.co.za
my email address is murray dot carte at oliviershoek dot co dot za
How can I change the email address in future?
