Issues uploading world file

[alfred_leth]

Hello i want to change from Aternos to Minehut, so i want to upload my own world to minehut.

Problem: When uploading the properly formatted .zip file (inside looks just like https://superleague.zendesk.com/hc/en-us/articles/360015767054-Downloading-and-uploading-survival-guide), it does not get added to my world files on Minehut. It doesn't even show an error message, but just the quick flash of an uploading bar that then immediately disappears, no result.

What i did: I downloaded the 3 world files from Aternos. I replaced the dimension files in the overworld file with the nether and end files to combine the 3 of them. I then compressed all the files using 7zip (not just the world file, but instead the files inside it). I have tested this .zip file and it plays fine if you upload it to Aternos from scratch or as a singleplayer file, so the problem isn't in the file.

Question: How do i get to play my world here? The reasons i changed was that i heard that this site is better than Aternos with stuff like render distance and chunk loading and such. I even tried replacing the individual files in the file manager with files from my zip file but that didnt work either. I only ask this question, since i think i'm out of other options. I would really appreciate an answer(:
