Same problem -> Noticed 10/28/2023 -> macOS Monterey v12.5.1 on Intel Mac; Tanki app ver 1.255.255 used to work fine no longer works "loading" message forever with green stripe and white tank logo on grey. Login page not reached. Very sad. Safari -> can log in, Battle loads to ~95%, Then 'SYSTEM ERROR; Lost server connection; ControlChannelDisconnectException'. Well, at least I know it's not just me.
