Issue with Tag Manager

Hi,

I configured plugin to manage GTM and insert my ID GTM – ….

In Chrome inspection/console i see that message:
GET https://www.googletagmanager.com/gtm.js?id=GTM-NM2KTW4 net::ERR_ABORTED 404
On fireworks same result.

It seems that the link is not reachable.
I try to found a solution in various topics but didn’t.

What can I do?
