CData CDS Connection Manager Error : [x:ic] System error : No such host is known

Hi

I’m getting the above error “[x:ic] System error : No such host is known” when trying to debug a DTS package in visual studio.

I’ve check the Organisation URL and all other settings are correct against production, which is working fine. I’ve also connected to the same host using a different application on my machine, so I don’t think it’s a firewall issue. I’ve tried Visual Studio 2022 and 2026.

Is there anywhere I can get more details on the error, or has anyone come across this before?

Thanks
