Q: Where can I open my map?

By default, it’s your servers public ip-address (e.g. 123.45.67.8) and the port (8100) like this: http://123.45.67.8:8100/
(Make sure you replace 123.45.67.8 with your server-ip. The same ip that you are using to connect to your minecraft-server!)

Q: I still can’t access the website!

Here is a checklist:

  • Is the port (8100 by default) open and forwarded correctly? Or is your firewall blocking incoming connections on the port? If you don’t know this ask your server-host how you can open a second port for BlueMap!.
  • Have you set the correct public ip of your server in the configuration? (E.g. ip: "123.45.67.8")
    Also try to use the default ip setting! (Have a # in front of the line to comment it out) This works on almost all servers!
  • Do you get a message saying Webserver started... in your server-console/log? If not, look if there are any errors/warnings and check the configuration again.

Q: I am getting 404 - Not Found when i open the map

Check your core.conf configuration file, did you set accept-download to true?
If yes, check if your webroot settings in render.conf and webserver.conf are set to the correct (same) folder.

Q: My map isn’t updating!

BlueMap needs to wait until the server saves the world data to disk, so it may take some time for changes to appear on the map. Also make sure to click Update Map in the menu on the left to make your browser fetch a fresh copy.

Q: I have black/pink-checkered blocks on my map!

Q: My block-textures are messed up when i zoom in on the map!

First, press the Update Map button in BlueMap’s menu. This updates all tiles from the server and makes sure your browser has not cached anything weird.
You can also try to clear your browser-cache completely. (F12 -> Network -> [x] Disable cache -> F5)

If that doesn’t help you might have changed some bluemap-settings that require a complete re-render of the map: Just use /bluemap purge <map-id> to delete and re-render the entire map. Then clear your browser-cache again, and it should be fixed :)

Q: I have a black map / a lot of the map is missing!

  • Press the Update Map button in BlueMap’s menu. This updates all tiles from the server and makes sure your browser has not cached anything weird.
  • BlueMap can only render the parts of your world that have already been generated by Minecraft! (E.g., by exploring your world or using a plugin to pre-generate an area of your world.)
  • Use the command /bluemap debug block (in-game). If that is throwing an error, it is likely that you have a mod installed that is not compatible with bluemap. Check the incompatibilities-list below. If you don’t have any mod from the list, please report the error here.
  • If nothing else works, you can try to set ignoreMissingLightData: true in your map configuration (render.conf).
    This will ignore potentially missing light data while rendering, with some drawbacks:
    • Cave-rendering will always be enabled, because it is using the sun-light data to detect the “caves”
    • Everything on the map will be rendered fully lit (sun-light value of 15, looks similar to having night-vision)

Q: The map (web-app) is really slow (lagging)

Make sure you have hardware-acceleration enabled on your browser! Use your favorite search engine to learn how to do this :)

Q: BlueMap does not find my world!

You have to add all your worlds to BlueMap’s render.conf!
BlueMap has the world-world preconfigured. If your world-folder is not called world (or world_nether/world_the_end on spigot/paper) then you will need to change the default’s in the render.conf.

Q: How can i add SSL (HTTPS) to my map?

BlueMaps integrated webserver does not (and will not) support SSL on its own, but you can e.g. use NGINX to reverse-proxy your map and add SSL that way.
