A VAC error is not a VAC ban. Something on your system is interfering with the proper operation of VAC.

As long as this interference impedes proper operation, you won't be able to play on secure servers.

Try with restarting your system first.

If you cannot pinpoint the cause of the issue, a reinstallation of your operating system is advised.

a vac error is never account related.

I suggest to try again on a system in which only the necessary software is installed. If it works, add more software until you find the culprit.

If it fails on both systems, then the software that causes it must be on both.

It is third party software on your system that is preventing VAC from performing correctly.
