I just fired up a Windows Sandbox VM and installed the latest Edge Dev build and the same issue is happening. I have cleared all cookies and site permissions for both sites (and all sites) and still no go. This issue affects all of my computers running Edge Dev logged in under my MS account (and not logged in). I get a 'Hmmm… can't reach this page The connection was reset.' Both sites open/work properly in Chrome which leads me to believe it is not a connection issue on my computer. It started out where I could not connect to any of the computers under my LogMeIn Central account and now it is happening to. A weird issue has started to crop up on my Edge Developer Chromium Version 80.0.345.0 (Official build) dev (64-bit).
