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.

My domain is: regix.tk / panel.regix.tk

I ran this command: certbot certonly --apache -d panel.regix.tk

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Certificate not yet due for renewal

You have an existing certificate that has exactly the same domains or certificate name you requested and isn't close to expiry.
(ref: /etc/letsencrypt/renewal/panel.regix.tk.conf)

What would you like to do?

1: Keep the existing certificate for now
2: Renew & replace the certificate (may be subject to CA rate limits)

Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2

Welcome @Frezze

I am about to sign-off for the night but want to warn you about rate limits. You got 5 certs for panel.regix.tk today. Any more attempts with that name in the next week will fail with a rate limit error. See your cert history here

You are not having any trouble getting certs. You must have some sort of problem configuring your server. Or, what looks like multiple problems. I get an http error 500 making an http request to that domain. And, https requests to your domain are refused.

Please wait for someone else to advise you about your server before you make an even bigger problem. Do not try deleting certs. Do not try revoking them. Those actions will make things worse.

Everything here has succeeded.

This is Certbot failing to subscribe you to the EFF mailing list. It's not a fatal error and won't affect your certificate or webserver. You can safely ignore this.

yeah really? But then it breaks off after that without asking me anything like the email address etc..

That format of the command only gets a cert. You need to configure the HTTPS (port 443) VirtualHost yourself. Had you not stated certonly the --apache plug-in would have configured apache HTTPS for you. It is not wrong to use certonly - I am just describing the behavior.

Alas, you cannot retry without certonly right now because you already used up your limit of certs for that specific domain name.

For assistance configuring apache and your VirtualHost, see:
