Some of our customers are getting to the confirmation of payment step in purchasing from our Magento store, and then they are getting a timeout error, where the SagePay payment gateway is trying to contact our server to tell it that a payment was successful (or not…) but it cannot contact our server, or cannot get a response from our server in a timely manner, and then the payment/order is being cancelled.
I've raised this question to my hosting company, but all they told me was:
"This is down to the way the software is configured on your server"
This is currently a Magento 126.96.36.199 standard installation as far as payment gateways are concerned. What on earth could this statement mean?
Is there some configuration that I need to do to make Magento listen to these requests and respond properly?
