I've imported 3 different web data connectors (Quandl, Reddit, Tableau's stock example) to my Tableau Server 9.2 and created multiple extracts and workbooks. The extracts contain the most recent data when they are created, however, when the schedule refreshes happen, the extracts do not containing any new data. There are no error messages. Each refresh says it succeeded and only took 1 or 2 seconds. We do have a proxy server. I configured gateway.public.host, gateway.public.port, gateway.trusted and gateway.trusted_hosts, but it did not change anything.
I'm at a loss as to what else I can do since Tableau support is unable to help with web data connector issues. Any help would be greatly appreciated
