What i did / Steps to reproduce

I downloaded the Bluemap, port forwarded the ports.

Expected result

For it to work.

Actual result

I can use only /bluemap reload, causes the server to not being able to shut down properly.
Nothing is hosted.

Context

BlueMap Version:
bluemap-5.5-paper
Server Version
This server is running Paper version 1.21.4-110-main@c44f891 (2025-01-14T11:13:21Z) (Implementing API version 1.21.4-R0.1-SNAPSHOT) You are running the latest version

• I used docker.
• The world was not generated using any mods.

Also:

• There is no debug logs. They generate empty
• I left it for one hour and still nothing.
• Config was left unmodified except the agreement on top.
• Server is not overloaded or anything.
• Its behind a proxy - Velocity.
• I tried deleting all other plugins (Produced the same results).
• I attached 3 screenshots.

It says:

Update, it is not empty.
dump.json

Please attach the full minecraft server log from server start to server-stop, the image you sent is only covering the server shutdown.
If able also attach the ./bluemap/logs/debug.log file.

So, the ./bluemap/logs/debug.log is empty.

Below is the full server log.
latest.log

Alright, looks like bluemap is somehow freezing while loading.. can you try running /bluemap debug dump after the server started and sending the file the command should create here, (if the command works)?

The command does not work.
I can send the logs with it invoked if you need.

Is there a full error, or just "that command doesn't exist" ?

The error is in the screenshot, it says to reload.
Im gonna try it again in a moment, maybe as the console it will work.

Alright, i can see in your dump.json that BlueMap is stuck trying to connect to mojang to download minecraft-resources .. it seems like the connection to download is stalling.
Make sure your server allows accessing the mojang servers (https://piston-meta.mojang.com/).

Alternatively you can download this file: https://piston-data.mojang.com/v1/objects/a7e5a6024bfd3cd614625aa05629adf760020304/client.jar
and save it here in your server: ./bluemap/minecraft-client-1.21.4.jar (named exactly like this). Then bluemap will skip the download step and continue loading.

Did not help, same issue (i ensured the name like two times)

Since it is stalling .. also try setting accept-download: false again so bluemap really doesn't even try to search for updates..

Your main issue is that the connection to mojang isn't working for some reason .. this is not an issue within bluemap but some problem with your setup.

Still, I will add a timeout to the connection-attempt so instead of stalling it will error in the future.

Ok, setting accept-download helped.

Have a great day
