Error Getting Buckets

So I have setup 12 of these for different sites but not come across this error before. The full error is

Error Getting Buckets — Error executing “ListBuckets” on “https://sfo3.digitaloceanspaces.com/”; AWS HTTP error: Client error: GET https://sfo3.digitaloceanspaces.com/ resulted in a 403 Forbidden response: AccessDeniedAccess Denied./AccessDeniedAccess Denied./not available

1. so I thought mybe an extra space etc in the code in the wp-config.php and no. The region is also correct.

2. I then tried my code from what I use on other sites that worked and not that did not work for this site either. So not the code in wp-config.php

3. Checked all the settings in digital oceans where the same for this new connection and all the others that worked and they are all the same. So not a permissions issue at digitaloceans.

4. Checked the permissions on cloudways (host) and cant see what is different.

Anyone else have any suggestions? Thanks in advance.
