So i use vpn apps (betternet, Surfeasy etc.) on my lg g2 d801 for torrents. They were working fine until a couple days ago. I cant connect to any vpn app. For all vpn apps when i press connect it says connecting for a splt second and then stops. I get no confirmation prompts to connect either. I know its not my internet cus i used a couple other peoples wifi. I tried clearing the data for all the apps but no luck. Know any fixes?
