Windows 10 update in February 2019 stopped Tversity Pro 3.8 from working on all my devices.
I first did a full uninstall and then reinstalled newest version of pro. I let the database rebuild. I still was not getting tversity to show up on any of my six different devices. I decided to try the following fixes:
I got this from https://support.microsoft.com/en-us/help/10741/windows-fix-network-connection-issues under the section called "run network troubleshooter"
In the search box on the taskbar, type Command prompt. The Command Prompt button will appear. To the right of it, select Run as administrator > Yes.
At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:
Type netsh winsock reset and select Enter.
Type netsh int ip reset and select Enter.
Type ipconfig /release and select Enter.
Type ipconfig /renew and select Enter.
Type ipconfig /flushdns and select Enter.
Windows let me do first three and then the fifth before I restarted.
Tversity came back on all devices immediately
