payment Not Complete error

[dev-becode]

I have done everything needed, I have it running on a verified domain with a SSL certificate, but it still always giving me payment not complete.

{
"epochTimestamp":1631532235832,
"expiresAt":1631535835832,
"merchantSessionIdentifier":"S............3",
"nonce":"6........6",
"merchantIdentifier":"DA.....2E",
"domainName":"Company.com",
"displayName":"Company Name",
"signature":"4 ...... 0",
"operationalAnalyticsIdentifier":"B2E",
"retries":0
}

I have checked the epochTimestamp and expiresAt
when I convert the epochTimestamp to time and date I get this date
epochTimestamp -----> Fri, 13 Mar 53671 22:50:32 +0000
CurrentDate -----> 13-Sep-2021 11:33:16

When you remove the last 3 digits from the epochTimestamp it gives the correct time.

In my code it reaches CompleteMerchantValidation then cancels right after that

onPaymentAuthorized and everything else runs before the session even begins
