Magsafe belkin 3-1 not charge the 12 Pro Max

Hi to everyone ,

As per the title, this morning I realize that Iphone 12 Pro Max does not charge if I put it on the belkin 3-1 base despite the green charging circle appearing; after a while the battery icon turns white and does not charge . I also removed the Mous magsafe case and tried with just the phone but it doesn't work either. I tried turning it off and on again since it happened a few months ago but this time it didn't work. It worked fine yesterday. What can it be ? Thank you
