Remote Control not connecting reliably
I have a Windows 10 PC with WSB 2.9.9, and an iPad with iOS 9.3.5 and WSB 2.9.9. Windows PC is the master, iPad is remote controller. First time I fire up the app on both, they find each other, and the iPad remotely controls the PC just fine. My firewall says it blocked a port scan, but WSB remote control works just fine.
Now I shut down WSB on the PC. iPad continues to show a network connection (solid red arrow in the network connection indication in WSB), but obviously its not really connected to anything. I launch WSB on PC again. iPad never finds PC. I try lots of other stuff -- shut down one, re-launch, shut down the other, re-launch. kill the app on both, re-launch. Disable firewall. Fixed server IP. Reboot iPad. Disable and re-enable Networked Mode. Nothing I do seems to let the two find each other again. If I put it away for a couple hours (or so), then try again, it all works.
I figure I'm missing something, but can't seem to stumble upon it. I see the Master status and IP address, and the remote's status and IP address. Both are on the same subnet.
One other thing --- once I check Use Fixed Server IP on the iPad, I cannot uncheck it. Touching that control seems to basically hang the app on the iPad.
Thanks in advance for any advice.
