Unable to import Excel Add in in Excel Online

Hi I have taken a sample github project https://github.com/OfficeDev/Excel-Add-in-JS-QuarterlySalesReport/blob/master/Readme.md , and after making a few changes in manifest was able to successfully import the add in in my desktop excel app Version 1611 Build 7571.2006 ( the add-in web app was running on my local box itself)

Now i am trying to upload this add on online excel, while my web app runs on my local box but I am getting this error on online excel

Here is the manifest i upload to online excel (this manifest file is same as the manifest which works on excel desktop except that i replaced the ip address from 127.0.0.1 to my public ip )

    <?xml version="1.0" encoding="UTF-8"?>

      <DefaultLocale>en-US</DefaultLocale>
      <DisplayName DefaultValue="ML LABSII" />
      <Description DefaultValue="ML LABSII"/>
     <Hosts>

     </Hosts>
      <DefaultSettings>

      </DefaultSettings>
      <Permissions>ReadWriteDocument</Permissions>
    </OfficeApp>

I have tried and the web app loads from other machine browsers with no issues.
