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 vary with individual users.

Ensure your PC meets our minimum system requirements. Your PC specs should match or be more powerful than the current minimum specs on steam. Anything less powerful risks having issues occur simply due to your hardware not being able to keep up with SCP:SL. As well, please ensure you are on an up-to-date version of Windows 11 and other operating systems are not supported at this time.

Resolution steps

• Perform a Clean Reinstall.
• Move the game to another drive. You can read Steam's guide here!
• Attempt to play SCP: SL with an Ethernet cable, if not already using one.
• 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 provider for further assistance.
