Is there some setting on the ORBI that prohibits LAN devices from seeing each other?
(One is on the 2.4Ghz WiFi and the other is on the 5Ghz WiFi, if that makes any difference.
The Guest WiFi has a provision to prohibit devices from contacting each other. My assumption is these devices are not on the Guest network.
2.4G vs. 5G has no relevance.
Windows computers default to "not respond to ICMP (ping)", which could explain not being able to ping in one (or both) directions.
Do you have a network scanner program that can test for open ports?

Ta Daa! That was the answer. Windows Firewall. I added a rule to allow my app port, and now all is well. Thanks!
I didn't realize that Windoze blocks ICMP by default.
