[GNC] Compiled release 5.6 - finance-quote not working

[osbert]

I have compiled the latest stable release 5.6 on Linux Mint. After 
installation, I am able to run the program, but the application fails at 
the finance-quotequery. I get the error 
"https://query2.finance.yahoo.com/v11/finance/quoteSummary/?symbol=AAPL&modules=price,summaryDetail,defaultKeyStatistics 
resulted in HTTP response 401 (Unauthorized)". What does it take to make 
finance-quote run successfully?

Here is what was executed:

cd build-gnucash-5.6
cmake CMAKE_INSTALL_PREFIX=/opt/gnucash -D WITH_PYTHON=ON ../source
make

sudo ./bin/gnc-fq-update
# std-output
# ...
# Test2 is up to date (1.302198).
# Finance::Quote is up to date (1.59).
# JSON::Parse is up to date (0.62).

sudo make install

gnucash --debug
# std-outupt

Thanks for any feedback on this matter.
