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: bardhome.de
I ran this command: certbot run -a manual -i nginx -d *.bardhome.de
It produced this output:

I entered the following text to my dns record at domainssaubillig.de:
_acme-challenge.example.com. 300 IN TXT "ODSRq86u-jtw1UoqMsfEpNOnMNjFM4DfuOJD_HGeUmM"
When I do the challenge for the subdomains manually (so no wildcard, but single domains p.ex. test.bardhome.de, subdomain.bardhome.de), its works. But I like to use the wildcard.
