[2.0.45] Fail to bind IPv6 bug

[ikiris]

"Binding IPV6 socket failed: Error code 10049, The requested address is not valid in its context."

When attempting to browse public server list get the fail to bind ipv6 socket when using NordVPN.

I expect this should just be an ignored error and y'all should implement happy eyeballshttps://en.wikipedia.org/wiki/Happy_Eyeballs properly.

I do have working ipv4/ipv6 dual stack on my normal network, and I do know what I'm doing otherwise (SRE / network engineer in RL).

Thanks for the report however I don't believe we will be doing anything about this. The networking in Factorio only supports binding to either an IPv4 address or an IPv6 address: not both/either. To change that would mean re-writing the engine networking logic and I don't see that happening at this point in development.
