Fix 1: Check Your Internet Speed
However, no matter whether you are using mobile data or a WiFi connection, you must hover over to the Speedtest.net website and run a speed test for your network connection. Meanwhile, in case you find that your device fails in the test, then you may need to contact your ISP provider and register a complaint against this. Thereafter, they will investigate and resolve the connection problem for you. In the meantime, keep in mind that whenever your internet starts working, the CS11 issue will automatically vanish.
Fix 2: Correctly Configure The Date And Time
A misconfigured date and time may also sometimes come up as the main cause behind this type of error. Generally, we do not pay attention to our device date and time, even though that’s the most crucial thing because almost every server-based application fails to function properly if your device’s date and time are misconfigured.
