I have setup a barebones install, and authenticated my bucket using the root user S3 credentials (just for now). Assets do not upload. I read a similar question here where the answer was that the response was being blocked by a firewall. I have tested on other connections and the issue wasn't resolved. Craft support suggested that I could edit some code on craft/app/lib/S3.PHP around line 771 but I'm not sure how to go about solving.

The problem was that Frankfurt and London are not currently supported S3 bucket locations in Craft CMS v2.6.2956. Switching to Ireland solved my issue.

  • How did you find out about this? Is it ever going to be supported in craft2?

  • Frankfurt and London are quite new S3 bucket locations. It will be supported but they have only just come out.

  • I asked in Craft Slack recently, these buckets will not be supported in Craft 2. Though they will be in Craft 3.
