Hmm, I was going to say the one below might help clarify things for you, but you’re saying your own domain, aren’t you?
In which case, I’m going to recommend an article from a couple years ago as it might help. This is a completely random suggestion I found and I can’t tell you if it’ll work. But at least wanted to put something out there.
If nothing else, it might help clarify things with your TXT code. I guess reply if you’ve already tried and not having luck, if it works, or what you end up doing.
