I’m getting disconnected from servers with the error “Processing of server security was too slow”!

Description of issue

This issue is typically caused by a variety of factors, which may vary between users.

Ensure your PC meets our minimum system requirements. Your PC specs should match or be more powerful than the current minimum system requirements on our Steam page. Anything less powerful risks having issues occur simply due to your hardware not being able to handle running SCP:SL. Additionally, please ensure you are on an up-to-date version of Windows 10/11. Other operating systems are not supported at this time.

Resolution

• Go to Cloudflare's Internet Speed Test and run a speed test.

  • If your download or upload speed is below 10 Mbps, the issue is likely due to slow internet.

• Move the game to another drive.

Try updating Intel drivers. Attempt to play SCP:SL with a VPN of your choice. Here is our list of VPNs. Should you be able to connect via a VPN, the issue lies with your internet connection - you should contact your internet service provider for further assistance. Attempt to connect to an Official server. Official servers are required to limit their plugin usage, and maintain specific standards of uptime and capability. This will rule out the issue lying with a specific community server or Geo-blocking from a region. Ensure all of your drivers are up-to-date, specifically your GPU drivers. Be sure to restart your PC after any updates. 

I still have issues!
