Hi guys.I play TW version in server 2 and i am Jr Master in the guild Akatsuki but sometimes when i invite someone to the guild,i keep receiving this kind of error:


and if i abort the operation this error appears:

It's like the game is losing connection and trying to restabilish the connection but it doesn't matter how long i let him restabilish the connection,the same process as in picture 3 is running.Can you help me fix this problem please?I will give thanks whoever help me correct this problem.
P.S:Sorry for my bad english
