Error: Can’t connect to Superhuman Go or Something went wrong

Note: Sometimes, this issue can be solved by restarting your computer. Make sure that you do so before proceeding to the steps below.

The “Something went wrong” error message is usually caused by restrictions within your network, VPN, proxy, or firewall settings.

To resolve this, ensure that your network, firewall, VPN, or proxy allows access to the following internet addresses:

  • *.grammarly.com (ports 80 and 443)
  • *.grammarly.io (ports 80 and 443)
  • *.grammarly.net (ports 80 and 443)

You or your IT administrator may need to add exception rules for the above addresses to your network, firewall, VPN, or proxy settings.

Additionally, Superhuman apps use WebSockets to communicate with our servers on ports 80 and 443. In addition to allowing the URLs mentioned above, ensure that your network, VPN, firewall, or proxy fully supports the WebSocket protocol. You can learn more about WebSocket support in this article: WebSockets Support Q&A for System Administrators

If this doesn’t help, we recommend following these troubleshooting steps for your operating system:
