Steam login process extremely slow when running under Sandboxie

[salehSKL]

Describe what you noticed and did

When I run Steam inside Sandboxie and attempt to log in, the process takes an unusually long time, around 10 to 15 minutes. The login screen remains stuck on "Logging in..." for this duration before finally completing the login.

How often did you encounter it so far?

every time I attempt to log in to Steam while running it through Sandboxie.

Expected behavior

Steam should log in within a reasonable amount of time, similar to how it performs outside of Sandboxie, where the login process is almost instantaneous.

Affected program

Steam

I have issue with Steam too. Actually with Valve Anti Cheat. I can play no more than 10 minutes, after this I get disconnected with error message "Client timed out." Relaunching game won't help, same error message instantly when try connect to server. Only relaunching Steam helps, but again no more than 10 minutes. BUT, I can play as long as I want if I'm only one player on the server. After disconnect and opening game console, there some text releated to VAC error code 5. There no info on Steam web-sites releated to this error code 5 (five).

I have Drop Admin Rights and make apps think they have admin rights enabled. Game is Left 4 Dead 2, but I sure in other Valve's games will be same problem.

It is possible to play VAC-enabled online games in sandbox? I read many other issues releated to Steam but they all don't solve problem. Issue releated to VAC or Steam Client Service, it can't perform some actions/checks inside sandbox.
