we use https://chart.googleapis.com/chart?chst=d_map_xpin_letter&chld=pin|5|808000|000000|FFFF00 for pin-generation.
since a few days we got an 404 response ...
i found already this topic: https://support.google.com/docs/thread/251700701 but it is about qr-code-generation.
does the generation of map pins no longer work? has the api been switched off?
try to get a pin-image, get an 404 error
Google has deprecated and retired the chart API. Please find the alternative i.e. https://quickchart.io/
