[GNC] Getting online Mutual Fund with gnucash

[The Tibetan Traveller]

I am having a strange issue with getting online quotes for mutual funds. 
Everything appears to be setup correctly since it works correctly for 
stocks.  However, of the 14 mutual funds I have (most are vanguard funds), 
I get a quote for one and only one vanguard mutual find.  I get a pop 
up window saying "Unable to retrieve quotes for these items:" and a list 
of all my other mutual funds.  I double checked the configuration for the 
one that works and one that does not work.  They are the same.

I didn't get any errors when checking with gnc-gq-helper.  The output from 
gnc-gq-helper on one of the MFs that do not work is:

(alphavantage "VSMAX")
(("VSMAX" (symbol . "VSMAX") (gnc:time-no-zone . "2018-12-21 12:00:00") 
(last . 60.7300) (currency . "USD")))

The various versions of the software I am using:

Distribution: Slackware 14.2
gnucash: 3.3
perl: 5.22
Finace::Quote - 1.47
