Thanks for the feedback. Sorry to hear you are in that position. It is limiting what we do too, to the point we may have to consider moving to a new host company. Which seems nonsensical - I have no idea why DH won’t support this even for private servers. It is something that even GoDaddy support, a bargain-basement host company IMHO.
My “guess” is, for whatever reason, it would be quite a lot of work for DH to do. And so they have decided for now they aren’t going to bother till demand grows to such a degree that it becomes untenable to not provide it any longer. It would be nice if DH were transparent about this, but thus far they have not explained why on this forum, nor in my support requests. That’s disappointing - we moved to DH many years ago mainly because we understood we could do anything with a private server. This is the first real obstacle we’ve been unable to work around.
