My issues generally stem from the UDP reliance of RP. Since my internet is now provided through my cell phone, It doesn’t play well.
I’m using a Windows 10 computer, which apparently doesn’t play well. Could have had an update go through that killed HC sum.
I’m sure this can be worked through, it’s just frustrating.
I know this doesn't help your situation and will be of little comfort, so just more as a so-you-are-aware response.
I too use Windows 10. Enterprise on one machine, Pro on another, and Home on yet another. Immaterial reasons why the differences. I can say with surety, at least in my case, RP works on all of them and no Windows updates to date have broken anything. The Enterprise machine has an extensive group policy arrangement yet RP still works. The Pro machine (my workhorse) has a tremendous amount of 3rd party software installed as well as many connected USB devices - printers, drives, scanner, drawing tablet, camera, etc. The Home machine is pretty basic with no external devices other than monitor.
My point is RP is known to work in varied Windows 10 environments. Unless you have some way out in left field Windows configuration I highly doubt Windows 10 or the updates is the reason for your troubles.
Let's talk about the Internet via cell phone shall we. I often create web apps for the clients of the company for which I work. Some of the apps are rather communication intensive relying on a lot of back and forth between the device and the server (AJAX). Guess where the vast majority of my complaint calls originate. You guessed it, people using cell phones to connect a computer to the Internet. They are usually in a meeting room at a hotel or some similar situation where they can't connect their laptop directly to wi-fi or a network. On the face of it everything should work yet I know from experience it often does not. Adding to their frustration is the fact that the web app may work fine on the phone in the instance but not on the connected computer. So in that regard I have a lot of empathy for Ring.
My experience with cellphone Internet connections for computers has shown them to be sporadic, problematic, and difficult to troubleshoot even when UDP is not in the picture.
Again, I know none of this helps you directly and yes, RP needs to step up their game with the software IMO. I say all this only so you know a) Windows 10 is likely not the problem; b) computer connectivity via cellphone often causes problems for more than just RP.
Keep the faith, brother.
