A couple of friends of mine are unable to connect to our private shard whilst sharing a network. When the second player tries to join, they are greeted with a confirmation of changes error. The shard is whitelisted(both are listed), but we have tried with whitelisting on and off. They are able to join other private shards together. Firewalls disabled, local connections, reset router, tried different ports. Shard is hosed by Fragnet. Anyone have experience with this issue?
