Android Question B4A 10.9 failing to wireless connect to Bridge

[kerryp24]

I have a Moto X4 running Android 9. Completely clean setup. I installed B4A Bridge. Installed fresh version of B4A 10.9.
Trying to connect B4A to bridge via the IP address shown on the phone.
Phone just keeps showing... Waiting for connection.
Status line of B4A keeps swinging between saying...

B4a-Bridge: Trying to connect...
AND
B4A-Bridge (motorola moto x4): Connected.

Connection between the two NEVER stays.
Computer is wired to router, phone is wifi'd to router (10 feet away).

Any thoughts on what is going on and how to fix it?
And, I have already reset the phone twice and exited/entered B4A twice. Doesn't help.
Also, I can PING the phones IP and I get response.

Check if you have any antivirus. Norton smart firewall can block connections.

It is not related to the new version as nothing has changed in regards to B4A-Bridge.

Is it possible that there are several instances of B4A running? This can will cause the connection to be "stolen" from one IDE to the other.

I am having this same issue but with a Pixel 3XL. Only one instance of B4A is running. Tried adding B4A as an app allowed through the firewall - no effect.
