Ok so I had the screenshare network support from Neptune and they weren't helpful in terms of resolving it. Support suggested putting it on another network with a router.
I added a router just for the apex and it's working well now with no disconnect for past 14 hours.
Seems like this is the easiest resolution. Buy a cheap router and put the apex on that new network.

I just went through the ringer with neptune for a good few hours a couple months ago, the best route is setting up a dedicated IP to run your apex on so it doesnt get confused.... that being said, like some of you have said, I set up a guest network to "trick" the apex and it has worked flawlessly for 4 months without a hiccup. My apex's hardwired connection doesnt work and I didnt care to send in for waranty so I did this instead.
