Hello,
I've attempted to connect to a few different APIs via an HTTPCaller using GET, in order to lookup UK postcodes based on a list of X & Y coordinates from a CSV file. The URLs being run through the workspace are all valid (I've clicked on them via the translation log, and they appear in internet explorer), but regardless of which API I try to connect to, I always get a 'Couldn't resolve host name' error returned. The APIs I'm connecting to require no authentication, so I that's not the issue. Is it possible the issue relate to restrictions with my corporate network?
