[GNC] Unable to retrieve quotes for these items:, CURRENCY:EUR

[rsbrux]

I am using GC 2.6.19 under Ubuntu Studio 18.04 and cannot get Online 
Quotes to work.

I have a few currencies enabled for quotation and several stocks. All of 
them work except for EUR.  My base currency is CHF

I have successfully tested all of the currencies for which I have Online 
Quotes enabled successfully using both gnc-fq-dump and gnc-fq-helper.

I have created a trace by:

 1. gnucash --debug
 2. Open Price Editor
 3. Get Quotes (error message appears)
 4. Close Price Editor
 5. Close GnuCash

However, I find no relevant info in the trace file.

I also repeated the above using gnucash --debug --extra, but the trace 
files appear the same.  the --extra option produced a lot of output in 
the terminal window, but nothing which appeared interesting or relevant.

Please advise on how to proceed.  Is anyone interested in my trace 
file?  What else can I do to troubleshoot this problem?
