Describe your issue
I’ve been having some technical problems with my Dynu DNS provider being partially incompatible with YunoHost. For instance, it gives me an error stating that the wildcard DNS record is not working:
['diagnosis_dns_missing_record', {'name': '*', 'ttl': 3600, 'type': 'A', 'value': '190.10.8.50', 'current': None}]
This leads to the Let’s Encrypt automated certificate install failing whenever I add a subdomain:
Skipping Let's Encrypt certificate attempt because there's no wildcard configured on the parent domain's DNS records.
Dynu, being both a DNS provider and a DDNS service, does not have a way to manually write the DNS record, only line-per-line through a specific form, in order to account for the dynamic DNS. It clearly shows there is a wildcard DNS, but only for the specific subdomain *.azkware.net, not for every possible subdomain - is this what causes YunoHost to assume there’s no wildcard at all?
