Paypal Sandbox down? (DAOSQLException: message 'Error on MAIN_TH'...)

[AndriesUrk]

Trying to integrate Paypal in my website, but I keep getting this error with the following stacktrace:

This has never happened before, any ideas? Is this an issue on PayPal's side?

Hello,

We experienced an issue within the sandbox environment yesterday which lasted approx 2-3 hours.

The issue has since been resolved.

Apologies for any inconvenience caused.
