I’m having an issue with Lets Encrypt and subservers where basically the SSL cert seems to be including the name for a completely different domain name on my server!
Not sure where its going wrong…
I have then created client1.domain.com and client2.domain.com as subservers, both websites work fine, but when I try and include them on the SSL cert (by using the ‘Domain names listed here’ it all seems to complete successfully, no error messages, but when I navigate to client1.domain.com (or client2.domain.com) I get this error NET::ERR_CERT_COMMON_NAME_INVALID which appears to be correct, because the SSL cert (when checking at sslshopper.com) is for an entirely different domain name (which does actually exist on my server and has it’s own SSL cert).
How could this of happened?
Any idea how to resolve or what to look at?
I forgot to add this, apologies:
