King of hill match cannot be started

Everytime I tried to start king of hill matches, it is showing "unable to start the match. Your team may be playing another match now or soon". My league match is starting 4 hours behind. So I tried to play with another team. Same result. I keep on trying to start the match every 10 s, and I have been trying that for 30 minutes already. It is still keep on saying that message.

Hey @Phyo

Challenge matches cannot be played during Top Eleven's daily update, so between 2:30-4:30am CEST. You should be able to play matches during all other windows.

We apoligize for the inconvenience.
