if you able to edit the lwc component, you can change line 98 (leafletMapFSC.js )

From L.tileLayer('http://{s}.google.com/vt/lyrs=m&x={x}&y={y}&z={z}', {

To

L.tileLayer('https://{s}.google.com/vt/lyrs=m&x={x}&y={y}&z={z}', {

my assumption is they don't allow http anymore, let me know if it works

thanks
