I recently had to reinstall Windows due to a hard drive change and WireShare no longer connects to the network. I searched this forum hoping to find a fix but to no avail as none of the indicated fixes refer to WireShare. I tried the other clients (clones) and while some do work straight out of the box, others don't and you have to apply a fix suggested in the sticky threads.
I tried everything suggested in the fix threads but nothing works - it looks to me like the only solution would be a fix like the ones for the clone clients but there isn't one for WireShare even though it should be since WS is the successor of LWPE.

Windows 10 (1809) running as administrator.
Windows Firewall (I added WireShare to the exception but no avail)
Connection type: Cable (fiber)
TP-Link TL-WR940N (everything is set up as UPnP)
WireShare 5.6.6. & Java 8 update 191
