PayPal Sandbox Error: Cookies are blocked

问题:

I was working with paypal sandbox account. It was working fine. But, now it shows the following error.

The cookies are enabled. I tried using different browser and a different computer. Still I'm getting the same error. I tried clearing the cookies and cache. But it didn't work. Any solution?

Please turn on cookies to check out

This is a Paypal's issue which affects Express Checkout on the PayPal Sandbox. Paypal announced that there is no alternative workaround at the moment.

This works for me: Paypal Sandbox Frustration

To simplify:

1. Login first your developer's account here: http://developer.paypal.com
2. Open another tab and login your developer's merchant account here: https://paypalmanager.sandbox.paypal.com/apiAccess.do?subaction=api
3. Open another tab again and do your express checkout process.

To add an experience : In the beginning I had serious SSL issues when connecting to sandbox for a SetExpressCheckout: The type of error was javax.net.ssl.SSLHandshakeException Error

To bypass this error (never happened before), i added the api-3t.sandbox.paypal.com certificate to my java truststore.

After that, the setCheckout responded correctly with a valid token, but I run into the 'cookie are turned off' problem, for almost 8 hours now. None of my websites is working with the sandbox environment.

I think nothing can be done until PayPal make things clearer with some announcement.
