error every time play clan match - can you make it so you can rejoin clan wars?

get a client error every single time I play clan war, really annoying as you can't rejoin and you leave your clan mates playing a clan war without you, usually its not just me who gets kicked so you end up leaving just 1 or 2 players against 4 or 5 of the other clan
can't you make it so we can rejoin a clan war?
