Can you try it again and not redact the authz this time? It doesn’t contain any sensitive information and contains valuable diagnostic information.

alright - didn’t know yet that it’s safe to publish the authz … good to know! :wink:

That’s your failure from ~an hour ago right?

The reason I’d like for you to try again is that your domain resolves fine right now, as you pointed out. An additional attempt should either succeed or reveal different errors.

alright - seems like I got some wrong Information firsthand … Domain was created in our DNS today and not a few days before as I was informed … so most likely DNS was just not propagated yet … sorry for stealing your time … :grimacing:
