So I am using Chroxy and ChromeRemoteInterface to fetch and further parse HTML with Floki. If I get the outer HTML inside the iex I am able to fetch and then find the elements I desire with Floki, however, outside of iex, Floki is not able to find anything.

ws_addr = Chroxy.connection()
{:ok, page} = ChromeRemoteInterface.PageSession.start_link(ws_addr)
ChromeRemoteInterface.RPC.Page.enable(page)
ChromeRemoteInterface.PageSession.subscribe(page, "Page.loadEventFired", self())
ChromeRemoteInterface.RPC.Page.navigate(page, %{url: url})
{:ok, dom} = ChromeRemoteInterface.RPC.DOM.getDocument(page)
nodeId  = dom["result"]["root"]["backendNodeId"]
{:ok, %{"result" => result}} = ChromeRemoteInterface.RPC.DOM.getOuterHTML(page, %{backendNodeId: nodeId})
pre_selected_content = Floki.find(result["outerHTML"], "div.productBoxTop")

Any ideas of what might be happening?
