Having trouble viewing Hubitat with Android Tablets

For a long time I was able to use my Android tablets to view Hubitat pages, dashboards, etc...

Then suddenly one day, for no apparent reason, the pages won't load on those tablets anymore. It works find on our Android phones, but the tablets just won't bring up the web pages. I've tried everything on them. Virus scans, full factory reset with data wipe, all with no luck.

Any ideas what might be happening?

What version of Android on the tablets and what browser?

Is it possible that your Hub’s IP has changed, such that links are broken on the tablets? Are you able to access the Diagnostic Tools page at YourHubIP:8081 on the tablets?
What model Hubitat? What firmware version? You need to provide us some information.

Nevermind, I got it sorted.

Most of the time my router doesn't care if my computer is on the 192.168.2.x network and the Hubitat is on 192.168.3.x. In fact, my PC is also on the 192.168.2.x network and has no issues getting to the Hubitat. I dropped in a firewall rule to forward between the 2 subnets and now the tablets are fine.
