But it is just your plugin with my keys and because I made this video and you can see a lot of keys are just in plain text I have removed all my exposed buckets and IAM users, so I don’t really get what you can do with this .zip
Isn’t it easier if you make your own EU bucket and test that on your end, should have the same results. All I had figured out is that is has to do with the signature version of AWS. As you can check here https://docs.aws.amazon.com/general/latest/gr/rande.html and search for the Amazon Simple Storage Service (Amazon S3) heading, you can see in the table Signature Version(s) Support some are Versions 2 and 4 and others are Version 4 only so I think this is the problem. I have a dozen of buckets in Frankfurt and this is Version 4 only.
It is already half a year for me that I am in need of a plugin like this. I first started with the fineuploader.com plugin but could not get it to work, so I was happily surprised to see that you did and because I have no idea how this stuff works, I was happy to buy your plugin.
