World keeps erroring out

    Hey so I wanted to make a 1.19.4 Aternos Minecraft server yesterday, so I downloaded a map to use. Every time I try and upload the world it gives me the 108 error message after like 10 minutes. The world is under 1gb. And the world is meant for 1.16.5, but I can still successfully use it right? And I saw that the 108 error might be internet related, and I don't have the best internet. But I've tried to upload the world like 5 times. Any help would be much appreciated.
