Connection failure for hybrid app toolkit on mac

Hi,

I am facing issue while testing connection of Hybrid Application Toolkit in sap web ide.

I have verified both port number and API Key in web ide and in config.json file.

I am unable to open "https://localhost:portnumber on google chrome. I tried adding this URL to exception list of chrome, but it not work.

I followed two blogs:

Install hybrid on mac

Install HAT on windows

None of them are working for me.

Please suggest how to fix this issue.

Thanks,

Saurabh.
