Dynmap Empty when zoomed out.

[IngeniousCoder]

Issue Description: Dynmap is EMPTY at default zoom despite fullrender and world generation completed

• Dynmap Version: 3.7-beta-5

• Server Version: paper 1.20.2

• Other Relevant Data/Screenshots: Dynmap when loaded into the site. Dynmap beginning to render once zooming in Dynmap partially loading at certain zoom Dynmap only loads after zooming even further

• Steps to Replicate: Literally just start a new fullrender of any world.

purge the map and fullrender it without restarting the server @IngeniousCoder

[IngeniousCoder]

Done it at least thrice. Same issue.

[JurgenKuyper]

did you purge, wait on finish and a new fullrender? not just a fullrender with existing tiles?

[IngeniousCoder]

Yes, purged. Manually verified all files gone in filesystem before fullrender.

Still error.

[JurgenKuyper]

then you are using a domain proxy that is caching the tiles, which might be wrong

I am validating from 127.0.0.1:8123, same issue.
