Amazon S3 Utils stopped working after upgrade to 22.2

Have you had the chance to look at the std out log? Are there any more details in there? Also, was this tested and working in a lower environment after upgrade? 

Here is another log entry we have noticed.

Looking at these errors, I do not think this is a plugin issue due to an upgrade. The second error easily points to a permissions set up on S3 - you need to check the authorization for account SCP. The first one is a bit more tricky but also likely due to an account issue, it could be that the key expired, or maybe even the account itself. That's where I would check first.

Thanks Mike.  We are starting to look at other places that might be causing the issue.   

Also, check the box in the admin console to ensure the plugin has access to the credentials that are specified. While unlikely, it's possible the upgrade removed that permission.

It is not checked. encountering same issue though i checked the box and gave a try

Yeah, check all the permissions on the account and its validity. I would also check any other policies that may restrict access to S3, like allow-lists on IP addresses, etc.

Thanks Mike.  We are back up running again.  There were more IPs that needed to be added to the Whitelist on the S3.
