I have the exact same issue.

for the Mac to iPhone you mention, is that with both the Mac and iPhone on the same network (or via VPN) or is that over the internet?
I emailed Blackmagic about it since 18.5 beta and 18.5 release, 18.5.1 and 18.6 seems to all have the same issue for me. I was directed by email support to find networking help in the forums... wasn't' very helpful unfortunately. I either think it is not a networking problem or there is special network configurations that need to be made to make this work but I have found no instructions/documentation on that anywhere with regard to using the Remote Monitor feature. And if it does exist, would love to be directed to where that info can be found.
I guess for starters, my bigger question now is: Is this Remote Monitor App meant to work only when the host resolve system and the remote monitor app are on the same network (either physically or via VPN or similar) or can it also work over the internet? I am realizing I haven't seen a clear answer of where/when the app should work.
For context, I am able to get it to work when everything is on the same local network. As soon as I move the iPad/iPhone with the remote app off that network, like a client who is at thier home or on set, i get that exact behavior you describe of once the host lets you in, it gets stuck there until the timeout.
I have tried using Mac and Linux as the host and have tired iPhone and iPad as the device running the Remote Monitoring app. I have tried with the host from my office (which does have some restrictive rules) as well as host from my home which is as simple as a network can be. They all fail to connect and time out.
