Trying to test a plugin and i can't get the Sandbox account hooked up cottevtly. Getting an error that says Sandbox could not prove it is sandbox.paypal.com, but the certificate is from www.sandbox.paypal.com. Likely cause may be a misconfiguration.
I have a business and facilitator sandbox account. Ashamedly, I admit I am not proficient at setting this up.
The certificate when you reach a sandbox checkout page will be for "www.sandbox.paypal.com", it does not include "sandbox.paypal.com" as an alternate name as you won't be reaching that domain whilst loading a checkout page.
Check with the plugin author, the expected certificate domain name should be "www.sandbox.paypal.com" for web-based payments.
