[] vac check failed

as of yesterday with the update and into today, ive been unable to play tower unite at all. maybe 80% of the time i try to join the plaza or a condo, i get a black screen after loading and i can only alt+f4 out of the game. if i manage that 20% and actually get in, ill be there for 2 seconds before i get booted out and get this error.

im not vac banned, i can play other games with vac like tf2, im not running any software that would trigger the error, my connection to steam is fine, ive verified the games files, ive repaired the steam service, ive reinstalled the game, still nothing works

This issue occurs when the game is unable to maintain a stable connection to Valve’s servers. I would recommend checking your network connections and see if there is anything on your network that might get in the way of your connection to Steam.

Here’s a guide that might help as well: https://support.steampowered.com/kb_article.php?ref=1456-EUDN-2493

if all else fails, consider reinstalling steam
i had this problem before and this is what worked for me
