how to resolve Recv failure: connection was reset error

Hi, I am trying to collect some images from google api, and I get recv errors when trying to save the file to a local folder,

>> websave('test.jpg', 'http://atlas-content-cdn.pixelsquid.com/stock-images/blue-yellow-basketball-ball-J3JE6aD-600.jpg')

Error using websave

Error connecting to http://atlas-content-cdn.pixelsquid.com/stock-images/blue-yellow-basketball-ball-J3JE6aD-600.jpg: Recv

failure: Connection was reset

I can access the url via chrome broswer, but not in matlab

Any idea what cause it, and how to fix it

Hi Yujin,

From what I understand, you're running into an error while trying to download an image using 'websave'.

I am not able to reproduce this issue, but the following steps might help in troubleshooting:

• Ensure MATLAB's "Web Preferences" are set correctly. Refer to this link: https://www.mathworks.com/help/matlab/matlab_env/web-preferences.html
• Try setting a higher timeout by adding a 'weboptions' object in the arguments of 'websave'. Refer to this link: https://www.mathworks.com/help/matlab/ref/weboptions.html
• You could also try using MATLAB's HTTP interface:

        import matlab.net.http.*
        url = 'http://atlas-content-cdn.pixelsquid.com/stock-images/blue-yellow-basketball-ball-J3JE6aD-600.jpg';
        filename = 'test.jpg';
        request = RequestMessage('GET');
        response = request.send(url);
        if response.StatusCode == 200
            imageData = response.Body.Data;
            imwrite(imageData,filename);
        end

Hope this helps!

I have added 'timeout' option to websave, it helped some cases, but other cases may be caused by the server end, so I have to drop any attempt with recv error.
