S3 failed upload large files bad request 400

Thank you for the suggestion. I have been testing my connection with this tool.

Through my tests I am getting high packet loss. I will take this to ISP to see if they can troubleshoot.

Here's all my testing outputs if anyone can find any insights. If @ncw is happy, I can make this has solved as this is not a problem with rclone tool.
