The connection issue might also be caused by at least one of the following safety measures within your infrastructure:

  • A proxy server prevents communication between the extension and your Canto account
  • A firewall prevents communication between the extension and your Canto account
  • An anti-virus software blocks aspects of the extension or limits communication
  • Permission sets within your network block aspects of the extension or limit communication
  • Permission sets on your local machine block aspects of the extension or limit communication

A simple test to verify whether or not communication is blocked by your infrastructure is to either set up a personal hotspot with a smartphone or to log in to another network (e. g. the Wi-Fi from home or a public cafe etc.) and try again.
