Need some professional support...

I've got a GAS project that imports several calendars from external URL:s. It joins two or more ics-files, renames calendar and change description - and creates new ics-files, saved on Drive.

I would like to call these new ics-calendars from an external calendar app - BUT the url generated by GAS wont work. It´s nothing wrong with the file - if I download the file and import it - everything works.

I´ve tried both importing the generated url into external program - and using the url in my own project: Using my generated file:s url in my project - the same problem.

My conclusion: The url, generated by GAS, calling to a file in Drive - doesn´t generate the same file/data as a url from a regular domain. I guess - it returns some other form of call. Is it possible to tweak the url? or - is it possible to save the file, with GAS, somewhere else?

I´ve tried: file.getUrl() and file.getDownloadUrl()

When I put the URL in a WEB-browser (Chrome) it shows the file in a window. SourceDAta when I use another program reports: Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?

....

Can I get atound this?! I would like to be able to call this URS with a GAS-script..., and Outlook, and ics-validator and... and..
