I truly hope the bugfix will come soon. However you really do not need to wait for that. Do the following step by step:
01. Open Eset console | 02. Click "Setup" | 03. Click "Advanced setup" | 04. Click "Web and email" | 05. Click " Web access protection" | 06. click "Web protocols" | 07. Now you are on the right place | 08. Focus on "Ports used by HTTPS protocol" | 09. You have to see the text "443, 0-65535" in the input field. | 10. Replace the text with "443, 0-8008, 8010-65535" (of course, without quotes) (you can copy-paste) | 11. Press "OK" | 12. If Windows asks for permission, press "Yes" | 13. Close ALL instances of Chrome | 14. Reopen Chrome | 15. Connect to your Chromecast | 16. Success!
After the bugfix will have been rolled out, you can reset the original text you modified.
