503 errors on Paypal checkout orders that are refunded

Good day wpgateways team

I am experiencing issues with orders that have been paid with paypal express. here is what is happening.

issue 1.
If an order has been made and payed for with paypal express checkout, the status of the order changes to processing. But once a dispute is filed by a customer, Paypal API changes the status to on-hod automatically. But sometimes this doesnt happen an the order is stuck somewhere between processing and on-hold. when i try to load the order either by searching for order number or by name. i get a 503 only for that order. i also get 503 for all tables which carry that order.

issue 2
this is similar to issue one, this happens when someone pays via paypal express and the order is changed to on-hold pending a payment to be cleared by issueing bank into paypal account. this can take a few days. so the paypal receives cash and sends command that the status should change to processing. however these order too get stuck in limbo, and any table that carries this order will result in a 503 error. searching for the order number or customer name results in a 503 error.

all other order using other gateways behave alright. so this is a paypal express problem.

please help me.

thank you

regards
