Problem activate dkim

Not able to activate dkim signing via api


Prerequisites to be completed:
- ordered hosted exchange
- used api.ovh.com (/email/exchange) to create dkim selector
https://help.ovhcloud.com/csm/en-dns-zone-dkim?id=kb_article_view&sysparm_article=KB0058258
- my domain is not hosted at ovh, but external. So I have to configure dns zone manualy
- seems to work. Several online dkim check tools tells me, that the configuration is ok.
- but ovh API always states:
{
customerRecord: "ovhex1131208-selector2._domainkey.mxdomain.cc"
lastUpdate: "2023-09-16T17:28:23+02:00"
selectorName: "ovhex1131208-selector2"
status: "waitingRecord"
recordType: "CNAME"
targetRecord: "ovhex1131208-selector2._domainkey.8166.ab.dkim.mail.ovh.net"
taskPendingId: 0
cnameIsValid: false
header: "from;to;subject;date"
}
So, the status waitingRecord is my problem. Never changed. Since over 24 hours.

Anybody an idea what iw wrong?
