[BUG] - App crash when configured for IPv6

[ShaunMaher]

Describe the bug If an IPv6 address is entered into the Interface -> Addresses field, (with or without also specifying an IPv4 address), the app crashes whenever it tries to establish a connection. This has worked fine until recently. Both manually establishing a connection using the UI, or enabling auto-tunnelling causes the crash.

From the log:
