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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
It produced this output:
"Logged at" 2021-06-14. There are no recent certificates logged here for our domain. But we are hitting this issue:
"Error creating new order :: too many certificates already issued for: neo4j.io:" (from acme.sh)
We see this for both your staging and production environments. However we should be able to issue 30,000 certs using the staging environment - and we don't think we have done anything like that many. 
According to  we should be able to figure out which certs have been issued, and work back to find if we have a leak in our automation.
I take it back - ARGH! I was not hallucinating but crt.sh is returning inconsistent results. Here is the same crt.sh url I used 5 minutes ago showing nothing since Jan 2021 and is what I saw originally. My url: https://crt.sh/?Identity=neo4j.io&deduplicate=Y
