Re: No connection could be made because the target machine actively refused it.
The server has the internet and it can even preview the data and set up the link.
Within the domain, the firewall is off. I think the client has some proxy server / firewall for the whole domain. I am not sure if the firewall for the domain is blocking the port. Will ask them to check but does the port 443 needs to be open when loading data from DataMarket?
