Hi John, If possible try to switch to the REST client (new feature of PB 2017) from the SOAP client (legacy feature of PB 11). We are deprecating the SOAP client and also the SOAP client is an old implementation that doesn't support TLS 1.2 security, but of course you could embed/call an external SOAP client if switching to a REST client is impossible for your project. Our REST client works for both 32-bit and 64-bit versions, supports TLS 1.2, symmetric and asymmetric encryption, OAuth tokens, data encoding (e.g. binary data, URLs, etc.), and can map multiple DataWindows to a single REST Web API. Here is a 3-minute YouTube video on the new REST client: https://youtu.be/sk8vlbV84ME
