iSro login failure to only one of their servers.

[WaKy]

Hello ePvPers, i am encountering a problem. Whenever i try to connect on my server(RedSea) with any of my accounts i get C9 error. What makes it weird is that i can connect any other server and everything runs smooth.
But in the same time i can't access the official site.
I tryed the following fixes :
> disabled / uninstalled my firewall /antivirus;
> reseted my router and looked into the firewall provided by the ISP (disabled)
> deleted any modification to the host file i had since now the servers are populated...

(Managed to log in two times in two different days but d/ced within 3 minutes)

I am getting quite angry on this stupid issue,so any help would be greatly appreciated.
(I did used the search button and read alot of the older posts about the same issue&tryed most of the fixes proposed so don't jump on me..)

the C - errors are serversided, but as i hear JM is fixing the loging errors.
they can be cause of the stat/skill resett potions from the Calendar event.
