Tried using an Ethernet Cable, restarting Router, Reinstalling the game, using an Alt Account to make a character with a different name, disabling IPv6, Making IPv4 Read 126.96.36.199 188.8.131.52 as mentioned in another guide. None of the above has fixed my problem. I am still logging in, I have no characters. When I go to create a character every single time it says 3101.
Not sure if deleting your character and try to recycle the name works, it might be stored and blocking it causing the 3101 error.
Try logging onto the forums "account" and looking at your Main, Alt and Mule and see if any names are attached to your account make sure its fully cleared if you've deleted them.
Next step is to see if you can make an alt or mule, and log in. Pretty sure its the name though
