Error: Connecting to the Grammarly server...

If you see an error message that says "Connecting to the Grammarly server…", or a "Not connected" notification pop-up in the online editor, this typically points to a problem with your network configuration. 

To work reliably, Grammarly needs a stable Internet connection. Either message can indicate a problem with your local network, your ISP, or your computer settings.

If you are on a work, school, hotel, or hospital public WiFi:

  • Check with your network administrator to make sure online services such as Grammarly are supported and not intentionally blocked.
  • Note that many public networks have limited bandwidth.

If you're using a cellular data network or satellite Internet:

  • If possible, try a different network. Cellular data and satellite Internet connections commonly have slower connections speeds than cable Internet or DSL.
