Multiple domains / 1 ip with letsencrypt

Hello

I need a little help:
- if I installed letsencrypt to a domain, how can I delete it, if I dont want anymore?
- I have one ip and multiple domains, when I install letsencrypt to a domain, its perfect, but when I installed to another domain, and check https:// than I got an error message: Error code: SSL_ERROR_BAD_CERT_DOMAIN and I see that The certificate is only valid for the first domain I added.

How can I solve this problem?

I have exactly same problems, could someone help?

Thanks

Are you use apache + nginx proxy ?

just apache

So its fine when I generate a certificate for the first domain, but the script using the same certificate for any addon domains, maybe it needs to be changed to generate new certificate for any new addon domains.

What apache version are you running?

I have found out recently, that if you run 2.2.* it wil work but not multiple domains.
If you upgrade (don't do this on a live server, test it on a dev) 2.4.* it will work.

upgrading/downgrading should always be tested first.... believe me don't do it!
