I seemed to have figured this out. Apparently on the Setup Visual Analyzer screen, when logged into SalesLogix Visual Analyzer, you need to add an @ to both URLs that reference the QlikView server. For some reason it appears that forces Anonymous Access.
File to Load on Startup: qvp://@<servername>:4747/Visual Analyzer.qvw
Server Location: qvp://@<servername>
After I changed those 2 settings and closed and re-open Visual Analyzer in SalesLogix, the error no longer appeared and I was able to bring up the dashboards.
