NLS tiles not loading

[redheadkelly]

MediaWiki running on XAMPP for Windows

• Maps version: 10.1.2 with leaflet-providers.js from 3/18
• MW version:1.39.6
• PHP version: 7.4.33
• SMW version (if applicable): 4.1.3

Using layers=NLS.### and service=leaflet, the osgb1888, osgb63k1885, and oslondon1k1893 layers do not load.

{{#display_map: center=57.7683, -3.9723 | 57.8235,-4.2324~Little Daan; 57° 45′ 04″ N 4° 02′ 22″ W~Shandwick House; 57.6710,-4.1766~Balblair, Cromarty |layers=NLS.osgb1888,NLS.osgb63k1885,NLS.oslondon1k1893,NLS.osgb1919 |service=leaflet |zoom=9 }}

This includes the 3 that are not loading for me plus osgb1919, which does load for me, just as a comparison.
