I'm facing this issue, and I don't understand why this is only happening on LAN cable connection to the router and fine on wireless?! I mean the router either does support NAT loopback or it doesn't, isn't that true?
The only solution I have found is spinning up a Local DNS or modifying host files but I just wanna know WHY it would only happen on LAN cable!
