Hi,
Sorry that you are seeing this issue.
1. Is this a new install of CodeMix or did it suddenly stop working post an update?
2. Please try the ‘Reload CodeMix Engine’ from command palette using Ctrl+Shift+P and see if the engine connects.
3. Can you please reach us via Live Chat (Help > CodeMix > Live Chat) to help us quickly diagnose the problem?
If you cannot initiate the Live Chat currently, then please share with us the .log file located at the workspace dir/.metadata/.log (change the file extension to .txt and attach it here)
Apologies for inconvenience caused.
