Wrong PowerDNS API Call.
When you try to issue a wildcard certificate with dns probe and use the powerdns api you get this error message:

obtain certificate error: error: one or more domains had a problem: [.example.com] [.example.com] acme: error presenting token: pdns: error talking to PDNS API: DNS Name '_acme-challenge.example.com' is not canonical [´example.com] [example.com] acme: error presenting token: pdns: error talking to PDNS API: DNS Name '_acme-challenge.example.com' is not canonical

I think powerdns is waiting for a "." add the end of the record.
