S2 character error

I got this error lately, after i log off from my character and try to log on again, this error appaers when I want to select my character. But with the second try i log on normally. Its not that bad, but it happens also on the clientless mode with ribot. So after i get dc, char log on(Login successful) but its NOT really logged into the game, so I cant bot 24/7, caz im a lot of the time afk.
Any solutions, or anyone also have/had s2 error?

i had it too, i got it 2times in row, then dissapeared xD
try to login one time with normal client.
