Hello,
I'm studying machine learning from coursera.org. I'm using Matlab R2015b academic license. I've got error message during the job submission.
!! Submission failed: unexpected error: Error using urlreadwrite (line 98) Error downloading URL. Your network connection may be down or your proxy settings improperly configured. !! Please try again later.
I tried to set off windows firewall & antivirus and also reinstall Windows. The problem is still the same. What should I do to solve it.
Thank for advance.

Hi llya,
The problem here is that although your browsers trust certificates signed by "Trustwave", MATLAB release R2013a does not (yet). You can manually add Trustwave or the specific certificate of the website which you are working with to MATLAB's trusted certificate store however. The following article on our website explains how you can do this:
I hope this helps answer your question.
Thanks,
Tushar

I download certificate for www-origin.coursera.org using Mozilla and then add it to MATLAB acerts file by Portede software. But nothing changes.
Moreover I tried to find the correct URL that I connected by writing urlConnection before try block in urlreadwrite function. I get this.
Java exception occurred: java.io.IOException: Server returned HTTP response code: 500 for URL: https://www-origin.coursera.org/api/onDemandProgrammingImmediateFormSubmissions.v1
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(Unknown
