I am trying to use the built in ACME service to issue certs using my local Technitium server.
Oddly I can see in the logs the validation record gets created (and deleted) by the script but it still fails out.
Since this is all local DNS based not HTTP there. The odd issue is it's being deleted before it can be validated which is what makes no sense. The removal happens before the validation so I am not sure if this is actually a bug. The API call works to create and delete but it seems a bit out of order...I have tried a higher record ttl but the issue appears to be the order of operations. The record is simply deleted before it's validated.
