Had a Server running on windows 10 without any problem. Dynmap worked perfectly.
Then I copied over the whole server to a linux (debian 11) machine. I installed the java jdk 16 and started the server.
It seemed like everything worked at first, but then I noticed that thr dynmap slowly replaced the already rendered tiles with blank tiles (same filename but fully transparent). There are no errors in the console while rendering or on server startup.

The image format is set to webp. I installed the libwebp tools both on the windows and linux machine so that should not be a problem.

fullrender, radiusrender, ... produce blank tiles as well.

purgmap clears all the map files but the new rendered tiles still are blank.

• Dynmap Version: 3.2-beta-2-spigotcd
• Server Version: Paper for 1.17.1 Build 196
• Pastebin of Configuration.txt: https://pastebin.com/3zS1b46d
• Server Host (if applicable): myself (Linux, Debian 11, Intel i5 - 9600K, Intel UHD Graphics)

I have looked at all other issues and this is not a duplicate
