Thanks for posting. Typically these symptoms are the result of a port being blocked on your network. What you are seeing is all of your other characters being able to connect via their various ports but one (or a range) may be blocked, causing that character to be inaccessible. PlayOnline may use any of the following ports. If you are using a router, please configure it to allow packets to pass through these ports.Port numbers that may be used by the PlayOnline server group. TCP 25, 80, 110, 443 and 50000 - 65535 UDP 50000 - 65535. You would also need to add port numbers that may be used by terminals such as the XBOX 360: TCP 1024 - 65535 UDP 50000 - 65535. For more information about how to configure your network settings, please refer to the instruction manual that came with your router or contact the manufacturer directly.
