I'm using an nginx server, and disabled dynmap's internal server.

• Dynmap Version: 3.1-beta-2-389
• Server Version: spigot 1.16.1
• Pastebin of Configuration.txt: https://pastebin.com/Uf1U1CrR
• Server Host (if applicable):
• Pastebin of crashlogs or other relevant logs: no error output
• Other Relevant Data: I'm using Windows w/ Nginx.
• Steps to Replicate: Disable internal webserver, then follow https://github.com/webbukkit/dynmap/wiki/External-Webserver-Basics

Reopen if reproducable on 3.3

Are you on windows with nginx?

Yes. I'm using Windows Server + Nginx.

Did you delete all your maps?

No, all data are there. I didn't delete anything.
