Ephesoft Version: 3x+
Issue: Fresh Install: Ephesoft Won’t Start/Connect: Windows Firewall On
Typically this will have a more pronounced affect when in a cluster. The server you are trying to start can’t connect to other components of ephesoft on other server’s because of firewall restrictions. To test if this is the case, turn the firewall off for all servers involved with ephesoft environment. If ephesoft functions with firewall off, but it is still necessary to turn firewall on per organization’s policies, work with your organization’s network admin to properly configure the firewall.
