I was getting the error 10105, When trying to login to my character. I ended up trying something that fixed my issue while i was on hold with support.

I am on midgardsormr. I have friends that i play with and they were not having the same error that i was having.

I went to another to server that was in the same data center as me and I created a new character.

After going though all the intro CSs I was able to login into the game. After that i logged out and deleted that character and was able to log back into my main.

I am not sure if this actually fixed the issue but it worked for me.

If anyone else can try and post the results to see if this fixes the 10105 error
