I cant load in without being kicked out of inactivity.

Hi.

Check this : I can’t enter the game / the game doesn't load.

It doesn't say anything about being kicked out by inactivity, when I join a game I see a green progress bar load slowly until It reaches to the end, after that it stops. about 1m later I get kicked out by inactivity. the game used to work fine after I cleared some browsing data, I cleared browsing history, Cookies and saved website data, cached data and files, download history, Form data. after that everytime I try to join a game I get kicked out by inactivity while I'm loading into any game, once I do receive the warning of being kicked out by inactivity, I close it out but I still see the green progress bar loading, so I have to exit out then search up tanki again.

Which browser are you using?

Try using standalone flash

Did you try running the game on the official tankionline client? You can download it from the homepage: http://tankionline.com/en/
