Where can I check this?

Hello Me and my friends had a server we played on and we finally decided to close it. We wanted to download the world for backup, however it keeps saying "unable to upload world" and gives an error. I was able to download the nether and the end but the overworld keeps giving an error. I'm guessing my overworld file is too big or something because we played and explored a lot. The end file was around 50 mb and the nether file was 130 mb and both downloaded successfully. What can I do to download my overworld? thanks
