Android server dropping connection to client

Hi,

As the title suggests, I'm using an Android server to host a USB device, which I am picking up on a Windows 10 64 Bit Client.

It used to work fine, until around a month ago, and now it keeps dropping the connection.

I tried using a different Android Tablet (Amazon Fire) and that is working fine.
I can also ping the tablet in question from the command prompt on the PC and it pings no problem.

If I connect the Fire tablet at the same time, it recognises that as Android2.local.:7575 and works fine.

I've disabled the Antivirus on the Android tablet just in case, although it used to work with the AV on, but no change.

Any ideas?

The Client log is as follows:

The app does occasionally appear to freeze on the tablet if I try and exit, again, a recent thing. I have uninstalled and re-installed the app both from Google Play, and Via this site.

Thanks in advance for any help you can offer!

Best regards,

Mark.
