It seems that Kaspersky started blocking Steam servers

[Rimanah]

As of today, Kaspersky began blocking Steam servers making me unable to use my Steam client fully. This issue was not there in the past, it is new. It makes me wonder, if it can be rolled back(there was an update not a long time ago, so I assume this was what caused it). Currently disabling Kaspersky completely makes Steam usable again, but clearly this solution isn’t optimal. 

Could this be fixed in the future and does anyone else experience compatibility issues with Steam?

Hello, thank you for the answer. Kaspersky doesn’t show any notification regarding the blocking, but I was able to fix the issue by disabling monitoring on ports 443 and 80. It must be a new problem, either on Steam’s or Kaspersky’s side.

Actually just disabling monitoring on port 443 fixed it.

Well, while It is a solution, I wouldn’t say the issue is fixed. This is essentially disabling Kaspersky’s functionality anywhere - a “brute force” solution. The issue still needs to be looked at and perhaps Steam needs to be whitelisted by Kaspersky to stopped it from being blocked.

Hello @Rimanah, 

1. IF Kaspersky is *blocking* Steam, it will show in the KIS Reports. 
2. Have you reported the issue to Steam? 
3.
