sudden problem with 'fetch' and FRED database

Hi, I haven't had problems using the Datafeed Toolbox and the 'fetch' command to retrieve FRED data until now. This is the error I get:

>> d = fetch(fred,'GDPC96') Index exceeds matrix dimensions.

Error in fred/fetch (line 94) d.Data = [datenum(str2num(tmp(:,1:4)),str2num(tmp(:,6:7)),str2num(tmp(:,9:10))) str2num(tmp(:,11:end))]; %#ok

Would appreciate any suggestions or comments. Thank you so much.

It's temperamental if you use the default url. It works if you change the url to 'https':

connect = fred('https://research.stlouisfed.org/fred2/'); d = fetch(connect,'GDPC96');

I am not able to connect to this URL. I just get the following message. Can anyone else get data from FRED? Error using fred (line 55) Unable to connect to given URL.
