Custom map won't upload/work

I downloaded a co-op map called Co-Op Complex I & II (1 world) on 1.8. I uploaded the map, waited for 20-30 minutes, then loads up a page where it says "Please select world to upload" or something similar. After clicking the right one, I wait for 30 seconds for something to happen, and then it gives me a gateway timed-out and shows me Aternos's Twitter. I then tried to start up the server, I then spawn in the middle of nowhere, and the seeds are different when I checked in the server and singleplayer.

Yes, I edited the names so that there wouldn't be spaces nor there would be special characters. I would highly appreciate any help just to get the map going so my friend and I could have a bunch of hours of funny moments and fails in this puzzle map.

Should I make it Vanilla instead of Craftbukkit as well?

• Command blocks have already been enabled for a long time, and I already tried reuploading it around 3 times already on Firefox and Chrome, though I am yet to try it on Microsoft Edge and Opera. I am also on Windows 10 and have adblockers but I have disabled them on Aternos.

Yes, everytime. It shows:

• Ray ID: 2c1daf8f89b528d2
• Your IP address: 92.97.110.108
• Error reference number: 504
• CloudFlare Location: Dubai

And I redownloaded the map a few times already, and the size is arond 57.5 MB

Alright, I just tried it today, and it works! Thanks a lot
