As I have checked I found that this error is due to Paypal pro is only available in US And Canada. But as you can see the paypal log. My country is US. Also my Paypal business account is of US. Still I am getting this error. I have contacted Paypal support they said their is no issue from Paypal side. My magento version is 1.9.3.0

Can anyone please help me?
