Great news! Since FHL 1.66, TH arena can be accessed direcly by double clicking at arena list window! It means that you no more need to change to the TH IP (64.251.22.174) to access it, instead, any one of the IPs (217.23.130.21; 83.149.244.5; 83.149.244.13) now allow to enter TH arena. Thanks to FHL team for the tweak!
