Issue with SES and syncing it with my wordpress smtp plugin

Hi It worked fine, but last week I noticed that some emails failed to be sent. I checked the SES dashboard and did not see any warning/error messages. I regenerated a few times the user thru Identity and Access Management (IAM) I opened a case with the plugin developer, but he assures me that the issue is not with their plugin I keep getting this error on my smtp plugin for wordpress SimpleEmailService::ListIdentities(): Sender - SignatureDoesNotMatch: Signature not yet current: 20220517T120546Z is still later than 20220517T120532Z (20220517T120032Z + 5 min.)
