I have the same issue. I have tried uploading multiple .zip worlds and nothing works. I have tried uploading a world that was 35 mb, 181 mb, and 600 mb and it gets to a 1/10th of uploading and it just pops up the error message. At first I thought the files were too large but I read on Aternos that the maximum size limit is 1 GB. The worlds I uploaded weren't survival worlds but SMP Earth worlds.
