I created several certs for several domains. All these certs have their own configuration file which is checked by certbot on a daily basis for renewal.
Now the first certificate was due to expire in 30 days. What has happened then is that certbot detected this. After what it however performed the challenges for all domains configured in all my different configuration files and not just for the domain due for renewal. Then, this is ok again, it renewed only the cert which was due for renewal.
What irritates me a lot is that the challenge was done for all domains and not just for the domain with the cert due to renewal. I do not think that this is expected behaviour so I’d rather ask here if I messed up something. Perhaps this is even expected or a bug or …?
Thanks for your time.
