CS: GO server errors can be due to Windows Defender Firewall blocking the game connecting with the server. Click the Turn Windows Defender Firewall on or off link. Select the Turn off Windows Defender Firewall options, and click the OK button.
Why is ping so high CS:GO?
Quite often high ping or lag will be due to a temporary network problem related to the routing of network traffic between you > your internet provider > our server provider. If you started the game via the launch button, try to connect to the server by using the IP address instead.
