Media are not uploading to Amazon S3

Tom, are you using cloudfront? Your screenshot shows you haven’t put anything in the cloudfront settings.

EDIT: But, if it’s not uploading the files, then it won’t change the URL, no matter if you are using cloudfront or not.

EDIT #2: Also, did you look in your error log on your server? I can access mine form my cpanel. That might give you some info.

Tom, see this for info on a different plugin that seems to work. I installed it on my test site, and it worked.

Hi TraciBunkers

Re: CloudFront.. Yeah, not using it at the moment (might look at that later) – but you’re right, I’m pretty sure it shouldn’t matter, because the problem happens before I get to that point.

Re: the error log… Ah, good idea! I don’t know why I didn’t do that before. The error is illuminating… And I wonder if this is happening because I’m using an EU bucket, rather than the default US one? The error I get is:

Error uploading /srv/www/mywebsite/releases/20140306132721/wp-content/uploads/2014/03/Fullscreen_07_03_2014_16_29.png to S3: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint: “wordpress-media-mywebsite.com.s3.amazonaws.com”., referer: https://mywebsite.com/wordpress/wp-admin/media-new.php

I guess to delve into this further, I should try and look at the code and see what endpoint it’s trying to use… Or see whether it’ll work with a US bucket…

Tom

Ah – yes, I’ve found the bug, I think.

In the plugin, the S3 endpoint is hardcoded to:

s3.amazonaws.com/BUCKETNAME

… which is “path-style syntax”. The s3.amazonaws.com only works for US buckets. For other regions, it has to be changed – for example, for an EU bucket, it should be:

https://s3-euwest-1.amazonaws.com/BUCKETNAME

So I think that’s why it’s not working for my EU bucket.

Another alternative (which works with all regions) is to change the syntax to use endpoints like this:

wordpress-media-mywebsite.com.s3.amazonaws.com

… Which should work for all regions.

I think that, in order to work with all regions, the code needs to be updated to work with domain-type URLs like the one above.

Tom

Tom, look some some of the previous threads if you haven’t already. I think I remember seeing some where people whose buckets weren’t in the US were having problems. And I think the plugin author gave some workarounds–but I’ve looked at so much info, I don’t really remember.

Okay – I’ve got a workaround for making this work with regions outside the US.

This can be fixed short-term by changing line 152 in wp-amazon-web-services-master/classes/amazon-web-services.php

FROM:

$args = array(
‘key’ => $this->get_access_key_id(),
‘secret’ => $this->get_secret_access_key()
);

TO:

$args = array(
‘key’ => $this->get_access_key_id(),
‘secret’ => $this->get_secret_access_key(),
‘region’ => ‘eu-west-1’
);

… Obviously this would need to be added to the admin interface instead of being hardcode here – but adding the region in does fix the problem, and images can now be uploaded to S3.

I guess an enhancement is to either add a “region” dropdown to the admin interface, or – better still – detect the region from the chosen bucket automatically.

Tom

Thanks heaps for this workaround Tom, it has worked perfectly for me. For anyone needing a bucket in the Sydney region change ‘region’ => ‘eu-west-1’ to ‘region’ => ‘ap-southeast-2’

Hi Mandy,

Ah – that’s really good news!

Tom

My problem was solved by editing my user policy to this –

{
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:ListBucket",
        "s3:GetBucketLocation",
        "s3:ListBucketMultipartUploads"
      ],
      "Resource": "arn:aws:s3:::celingest-cdn",
      "Condition": {}
    },
    {
      "Action": [
        "s3:AbortMultipartUpload",
        "s3:DeleteObject*",
        "s3:GetObject*",
        "s3:PutObject*"
      ],
      "Effect": "Allow",
      "Resource": [
        "arn:aws:s3:::celingest-cdn/*"
      ]
    },
    {
      "Effect": "Allow",
      "Action": "s3:ListAllMyBuckets",
      "Resource": "*",
      "Condition": {}
    }
  ]
}

@tomkerswill

Thank you. That saved some time working it out myself.

And, yes, I agree that an admin dropdown would be ideal.
