Disconnected From Serveur

[Otaku13]

Hello,

First of all, I am French, so sorry if I express myself badly.

I am here today to ask for help because I have encountered a problem since yesterday ...
I play on a server (not mine) and since yesterday, as soon as I leave Drop etc on other map, I get disconnected randomly.
This never happens to the capital, only when I go into dungeons.
I do not know if this is a coincidence, but the same day I had an update from my Box that is switching to IPv6.

I do not know where it can come from, my connection does not shut down, only the Ragnarok server ...

I have a lot look on the internet, I reinstall the Client, patched, and still the same problem, and I can not find a similar case.

Thank you for your help.

Yep only me since yesterday, i asked the GM but he dont know too..

EDIT :
He gave me this crash log

EDIT 2 : 
I disable IPv6 on my box, and still have "Disconnected From Server"
