Version 6

That error message means the connection timed out, which is a fancy way of saying your tablet could not connect to Blue Iris.

Double check these things:
1. That the URL matches exactly between working and non-working machines; that 192.168.1.103 is the Blue Iris computer's IP address on your LAN, and that 7781 is the port number its web server is listening on.
2. The tablet is connected to the correct network (e.g. not a guest network or a neighbor's or cellular, etc).

I tried different computers; the same issues occur when loading UI3. Also, double-check that you're on the correct network.

Here my setup from BI,

UI3 Stoped to work after upgrade to version 6

Well that configuration all looks fine to me, so I suggest you create a new Windows Firewall rule to allow inbound TCP traffic on port 7781, for all network types. In case it is Windows Firewall blocking it.
