How to set WebRoot to ensure that correct ports are open

from Stardock Forums

Under Active Connections WebRoot AV shows that multisrv.exe and multipl2.exe are allowed, but the "PID" list doesn't show the ports Multiplicity uses. Is there something else I should check in WebRoot? I'm trying to troubleshoot failed Multiplicity 344 KM operation after installing April 2018 Windows feature update; it worked correctly with previous Windows 10 version, so WebRoot probably isn't the issue.

Webroot (specifically and notoriously) causes problems with MP.  If you turn if off, does it work?

No, Multiplicity isn't working now even with both WebRoot and Windows Defender firewalls turned off -- my question is in perusing any likely causes. Multiplicity has worked before yesterday's Windows 10 update, so I imagine the problem has to do with some change with the Windows 10 version 1803 update. Are others seeing this issue?

@sdRohan: Thanks, reinstallation got Multiplicity working. Evidently WebRoot handled whitelisting the necessary ports automatically.

That is good to hear but WebRoot has been brutal with MP functionality in the past - if you notice any other oddities, please let me know.
