Trouble Uploading World

I am having trouble uploading my world. Here are the things i have done to try and get it to upload:

I checked for unnecessary files and there was none. I watched the video on uploading a world and it didn't help. I renamed the file "world". I made sure it was zipped. I tried using a diffrent browser, it worked better but still didnt upload. The file isnt too big either.

There is no tick, it just stops uploading around 3/4 of the way.The version is 1.12.2. Please help

The file size is 150mb.

I don't know if you mean actual time, like minutes, or like how much it loads before it stops so: I would say it loads for about an estimated 15 minutes, and it loads to basically exactly 3/4 of the way before stopping.

I originally was using Google Chrome, and when i did that i only got about 1/4 - 1/2 of the way loaded. I recently tried Mozilla FireFox, and thats when it started loading to about 3/4 of the way. I've been using FireFox to try and upload it since.

Did you mean to say isn't? If not, is that supposed to mean that aternos cant upload that big of a file but my internet can? If you did mean to say isn't ,my internet does happen to be pretty bad.

Ok Ever since i couldn't upload it I've been working on a re-creation of the world so its ok that it wont upload i guess. I really appreciate the help though! Thank you for your time!
