Using MAP with background image (GREY MAP) help

[Klomorax]

Hello

I am trying to overlay an AUTOCAD drawing (converted to PDF then PNG) which I have uploaded to google drive

I have X/Y coordinates setup in data so I can use pinpoints which will show more data about it

It shows the pin but just grey nothing image on the map display. I thought it might be an image problem so I tried a random pic of a tiger, still same issue

I tried changing host (image host) to Unsplash still same thing?

I have embeded the google drive link with " in the expressions and nothing works!

I'm quite desperate to get this to work :)(
