Interesting Connection Issue

[jaren2099]

I'm not entirely sure this is happening to anyone else who tries to connect (I haven't heard anything from anyone else). But a player tries to connect to a shard I have running (currently 1.0 until I finish porting everything to 2.0) he gets the log in screen and that works fine (I'm verifying this from the console window) but as soon as the valid credentials for 'account' is displayed it says Player is reconnecting to 255.255.255.255 then disconnects them and they can't connect. I'm not sure if this is a router issue (if it is, it hasn't been in the past) or what is up. He gets a message on his end that says "Client wont attach". Any ideas on if this is a problem on my end or his?

sounds like a problems with your custom serverlist.cs file

[jaren2099]

Ah. I meant to actually attach that to the last post. But here is my ServerList.cs file:

// ==================================================================================================
// ServerList.cs
// ==================================================================================================
//    	1.0 	RunUO Beta 36	Initial version
//    	1.1 	Mr Fixit	Now automaticly detects if you are connecting localy and uses the
//				servers local ip in the client serverlist.
//	1.2	Mr Fixit	Internet IP autodetection using www.whatismyip.com.
//  	1.3	Mr Fixit	If script fails to find the internet ip, keep the old one and try
//				again in # minutes.
//      1.4	Mr Fixit	You can now add AutoIP mirrors. Added whatismyip.com and myip.com.
//      1.5	Mr Fixit	Adjusted the AutoIP mirror engine so it supports more mirrors.
//				Added findmyip.com and ipaddy.com.
//      1.6	Mr Fixit	IP is now trimmed (Just in case). Added simflex.com, edpsciences.com,
//				ipid.shat.net and checkip.dyndns.org.
//      1.7     Mr Fixit        Removed www.whatismyip.com is it seems to be out of buisness.
//      1.8     Mr Fixit        Added a message to the console with ServerList.cs version when server loads.
//				Now detects the internet ip when the server starts.
//				Now checks if the ip has changed every 60 minutes instead of 30 minutes.
//      1.9     Mr Fixit        Removed noip.com mirror as it isnt working anymore.
//      2.0     Mr Fixit        Now only renews the ip every 24 hours (1440 minutes).
