Error on Order Import
Error Code: INVALID_LOGIN_IP
Error Message: 'Invalid login. IP Address does not match any of the IP Address rules specified for this entity.'
Reason: NetSuite has IP address rules restrictions enabled which is not allowing Magento IP to import the order to NetSuite.
Under Setup > Company > Enable Features > Company tab > Access subtab > IP Address Rules, there are some IP rules to allow only specific IPs to place customers. Make sure that the list is correct and it allows the Magento IP the proper role.
