It's my first post here as I have inherited a nopCommerce system.
Due to a server failure, we have had to move a Nop site to a new box. Everything is working, except for the final checkout, where the system contacts Sagepay.
This is the message that comes up when trying to check out.
Your server was unable to register this transaction with Sage Pay. Check that you do not have a firewall restricting the POST and that your server can correctly resolve the address https://live.sagepay.com/gateway/service/vspserver-register.vsp.
The Status Number is: SendFailure
The Description given is: The underlying connection was closed: An unexpected error occurred on a send.
When I press next again, it says
Transaction Id does not exist or it is empty.
I have connected to the server and confirmed that the server can resolve that url, which it can no problem.
The system is NopCommerce 3.30
The Plugin it seems to be using is
Author: Microlite Software
The system was rebuilt from a complete database backup and copy of the website that was in inetpub. I have gone through the nop admin warnings and cleared them all off.
One thing I have noticed is within the sagepay plugin, everything is completed, except for the Partner ID. Could this be the cause of it? Although I would have thought that if this was completed on the old dead server, its values would have been in the database along with all the other settings for sage pay.
I would be very grateful for any help.
