Hi,
Sorry that you are seeing these issues. I assume you are working with the latest CodeMix release i.e 2019.12.11. If no, then please update to the latest via Help > Check for Updates and see if the issues persists.
1. Can you please clarify if Live Preview and Debug in Chrome ever work before? Is the problem with a specific project in the workspace or in other projects as well.
2. Is the app started and running in the Web Applications under Servers view?
3. When a change is made to the HTML file and saved, at that point, is the Live Preview pane turned on? If possible, please attach a screenshot of the workspace showing the Live Preview pane to help us get a visual.
4. Are you currently running the trial license? Please go to Help > CodeMix > Update License and let us know when your license is expiring.
5. Please share with us the .log file located in the workspace dir/.metadata/.log for further investigation (change the extension to .txt and attach it here)
Alternatively, you can reach us via Live Chat (Help > CodeMix > Live Chat) for a quick diagnosis of the issue. It is easier for us to gather the required information via Live Chat.
Apologies for inconvenience caused.
