Hello
I have set up my disk station again.
Now I try to reactivate the websites that are running on the DS.
I got some of them working again.
Now I wanted to call up a certificate for a website and get this message "The number of certificates issued by Let's Encrypt for your domain has reached the upper limit".
This website already had a certificate.
Is it possible to delete or reassign unused certificates?
You can download certificates from the crt.sh website above, but they are useless without the corresponding private keys, which are not downloadable, as they're, well, private..
You should wait until the rate limit has been raised (it's a limit of 5 duplicate certs in a sliding window of 7 days) and after that you should set up your setup permanently in a single go and don't re-setup again and again.
