No certificate matches private key

[zeepay]

Hello Guys,

I've been encountering this error for a while in completing the "Create Keystores" step for go live.

The private key & CSRs are generated (using openssl) and uploaded and the cert is issued.

The final step of generating a "PKCS" file out of the certs keeps failing with the error message "No certificate matches private key"

Does anybody have any suggestions as to how to work around this please.

Thanks.

Hey @zeepay,

Here is an example of how I generated a CSR File and submitted it to the Visa Developer Portal Visa Account Updater Project successfully. Please kindly use my example below as an example to help you generate the CSR and client key store (e.g. the JKS file / clientkeystore.jks ). Please follow step by step shown below but instead please enter in your own data (e.g. replace my data with your own). Please let us know if you have questions.
