I'm using yahoo_get with my students and they have had problems getting the data.  

They are using computers with Windows 10 and the Gretl version 2022-02-02. Some students with the latest Gretl version have had the same problem. 

We have used the following code: 

include yahoo_get.gfn #package

nulldata 10220
setobs 7 1946-01-01 --time-series
SP500 = yahoo_price("^GSPC", 1) #SP500

After that, they get this message: "data error". 

Meanwhile, I get the data without any inconvenient (I'm using Windows 10 Education and the last Gretl version) 

Any clues? The server? any security certificate?

Kind regards
