For it to work.

Nothing is hosted.

• 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.

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.

[Imistrz21]

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)?

[Imistrz21]

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

[TBlueF]

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

[Imistrz21]

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.

[Imistrz21]

It says:

Update, it is not empty.
dump.json

[TBlueF]

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.

[Imistrz21]

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

[TBlueF]

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

[TBlueF]

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.

[Imistrz21]

Ok, setting accept-download helped.

Have a great day
