Hey is there a option to get a new certificate for just a sub domain? Lets say my site runs on server A on example.com www.example.com and blog.example.com - the subdomain cloud.example.com points to server B. Is there a option with the certbot to get this setup running? I didn’t succeed. Both ser…

Hi @Gurkengewuerz , what did you try to do and how did it fail? Are you trying to use server A to get the certificate that will ultimately be used on server B? Or are you using server B exclusively? Or did you want two different certificates, one for www.example.com and blog.example.com and the othe…

@schoen thank you for your answer. On server A I used this command: ./certbot-auto certonly --standalone --email info@example.com --agree-tos --rsa-key-size 4096 -d example.com -d www.example.com -d blog.example.com And on server B that command (here also runs a other full Domain, which fine): .…

@Gurkengewuerz , what you described should work fine; I can’t think of any problem with this. If you encountered a problem, I don’t think it’s related to the content of the certificates that you’re requesting. Maybe you can give us some more specific information about error messages you encountered?

Based on what I think you want, just don’t specify a domain that the server can’t pass verification. That should mean for server B, just use “-d cloud.example.com ” and drop the “-d www.example.com ”. Assuming you pass the verification, you’ll get a certificate only for cloud.example.com .

Yes indeed, just request the certificate for the subdomain you want. So if you want a cert for only secure.mydomain.com then just request that one certificate. When you need a cert for another subdomain private.mydomain.com at a later date then request it when needed. My root domain spans across 4 U…

Thanks all I will try I today. Is there a option to begin from the start? Could I just delete /etc/letsencrypt/live and submit a new one?

Also add the --dry-run flag onto the end of the certbot command so you can see output / errors before you actually generate a cert.

@all Thanks for your help. I Dont know what was wrong in the configuration. I backuped the full /etc/letsencrypt directory and started everything from new. Now it works fine :wink: Thanks for your time.

Awesome glad it’s all working now, have fun :wink:

First back up /etc/letsencrypt/live before you try that. Are there currently certs in that folder?
