The file in question is on a network drive. I'm running the workflow at the office on my local machine connected to the network. If I run the workflow from the scheduler it works fine. If I run it at home on the same machine wirelessly connected to via a VPN to my office network it runs fine. It just won't run locally hardwired directly to the network. It's a 4GB csv file.
Sometimes the workflow runs for 30 mins or so sometimes almost 2 hours.
*DISCLAIMER: I'm an Alteryx newbie and this workflow was handed down to me.
