Yesterday in the morning everything was ok and since I didn't change anything also nothing on the API class. My Server support the sha256 and the protocol Tls12.

I've nothing in the Logfile from server.

The Live environment works fine but the sandbox environment doesn't work since yesterday.

Is it an error on paypal site or on my side? I've send also a mail to paypal but I get an autoresponse Message.

Please help me and sry for my bad english.

Thanks and best regards.

This may be related to the recent sandbox downtime over the past 24 hours or so. The problem was diagnosed by the team and they were able to repair the problem. Can you check again to see if it's working now please?
