Error: Connection reset or Connection refused

[Vivekanand Singh]

Hi Team,

I am trying to decrypt the google-pay token using the tink library. While doing so getting an error like

Connection reset or Connection refused in my prod environment same setup worked fine in the lower environment. Anyone faced this kind of issue.

Thanks in advance.

Regards,

Vivek

The library will attempt to download the public keys from

* https://payments.developers.google.com/paymentmethodtoken/keys.json for production, and

* https://payments.developers.google.com/paymentmethodtoken/test/keys.json for test.

Thanks, Thai Duong!

For a quick reply, for the same reason, I kept the key in some static file so no need to have the server to server call during decryption.

Any further suggestions will be appreciable.

Can you share some code showing how you're calling Tink?

decryptedResponse = new PaymentMethodTokenRecipient.Builder()
.fetchSenderVerifyingKeysWith(GooglePaymentsPublicKeysManager.INSTANCE_PRODUCTION)
.senderVerifyingKeys(verifyingKeys) //Static value public key
.recipientId(MerchantId) // Static merchantId
.protocolVersion("ECv2")
.addRecipientPrivateKey(MERCHANT_PRIVATE_KEY_BASE64).build()
.unseal(encryptedDataFromGPay);

Remove fetchSenderVerifyingKeysWith and try again to see if it works.
