Your shard id is 356
For example:
http://www.joinuo.com/Shard/356You have still not told me if you are using RunUO or another emulator, although I've asked a couple times. It's difficult to help with so little info.
The shard is not accepting connections from the poller; If RunUO: this may mean that you modified files in Scripts\Engines\RemoteAdmin
If this is another emulator I don't know what to say.
If ConnectUO is unable to poll you as well something changed on your end. I would have to guess what.
