Downloading world

Hello

I want to transfer my server world to a custom server and everything we did on the world was gone when I booted my custom server. I think the issue is with the world downloading. Can you please help me?

Thanks in advance

Edit: It is not the downloading

Is your server cracked?

no

Does it work if you try to load the map in singleplayer?

Yes, that works

No, the aternos server started in 1.16.1, and was upgraded later to 1.16.4. Now, I am using the 1.16.4 jar file downloaded from Mojang.

O jea, and I did a pre-test with a generated world

I did that already and only have got 1 world in the server folder

If you want to see my file structure and startup file, here it is (edit, without the world)

Now it works suddenly. Thanks Toothy for thinking with me
