My only guess would be the server can't handle the traffic because you are hosting on a home connection. I know for a fact the login server is working fine on the current revision.
We have three major servers with around 100 cocurrent players on each of them, and none of them have had any issues with their login server not accepting people.
Given that you are hosting a home, it is hard to troubleshoot any realistic problems since your bandwidth is limited by your ISP. They could also be rejecting specific port-bound packets after a traffic limit is reached too. It's hard to say since a lot of ISPs do various things to help limit bandwidth when caps are starting to be hit.
Logins stuck at acquiring player data.
Re: Logins stuck at acquiring player data.
No caps, no throttling, my ISP is aware of the server and they have no issues with it. I can host the server, a web server, they even allow torrenting. ISP checked ports and said they can see me and they are not blocking them.
