aws s3 cp 'Connection aborted.', ConnectionResetError(104, 'Connection reset by peer')

I am actually writing a simple script to zip a local game save then upload the zip file into my s3 bucket.

Somehow it gives me this error though. The most I can find googling around is about filesize + adding --region init which doesn't help at all.

somehow for testing, I created an empty folder, with just a random text file with random words in it. Let's call the folder name AA

I zipped it using zip -r filename.zip AA the zip works fine

Then I do the s3 cp as such

aws s3 cp filename.zip s3://BUCKET_NAME/public/ --profile myProfile

This works fine though, then I changed the folder name to my game save name let's say it's called BB then I did aws s3 cp filename.zip s3://BUCKET_NAME/public/ --profile myProfile again then I get the error of

upload failed: ./filename.zip to s3://BUCKET_NAME/public/filename.zip ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))

The folder is only approx 5mb and after zipped, it's approx 500kb. So size wouldn't have been the matter even though I did try to get the ./aws/config and add the bandwith.

If I create another new folder with random files inside let's say folder name is CC. It would work.

If I changed the folder name of the actually folder I want to upload after zipped. I get the same error.

Is there any restriction on what files can / cannot be uploaded to aws? Or else what might be the reason? I can't really think of much though.

Thanks in advance for any suggestions / advices.
