Automatically failover to LocalAddresses

[Biztactix-Ryan]

Is your feature request related to a problem? Please describe.
Can't connect to servers if it has a public IP Address as well as a local, Most Routers don't support Hairpin NAT correctly.

Describe the solution you'd like
Upon failure, if there are LocalIPs listed, then create a URI for each of them and check if you can connect to it.

Describe alternatives you've considered
I've tested it myself by overriding the Host on the AccountServer object, That works and I can continue from here... But obviously auto failover makes sense

Additional context
It's Ugly, but it shows where I've gotten to with it, It just catches the error and then updates the host

Ran into the exact same problem and used your code verbatim.. problem solved!
Thanks, saved me so much time.

Still Ugly but maybe less ugly extension method:

MyServer = services.ConnectToPlexServer(key, servername);

Extension Method

I'll try to take a look at this this weekend.

Thanks... Your code is much nicer, I wasn't particularly in the mood for nice by that point, the plex bit was supposed to be the easy part ;)
The old, I'll just write a quick bit of code to pull a list of all the shows I watch on Plex... and why isn't that working....
