I can read from url's and api's just fine as long as the return format is not JSON. Some examples from matlab help that don't work for me
>> api = 'http://climatedataapi.worldbank.org/climateweb/rest/v1/';
url = [api 'country/cru/tas/year/USA'];
S = webread(url)
S =
Empty matrix: 0-by-1
But this works just fine:
fullURL = ['http://www.mathworks.com/matlabcentral/fileexchange' ...
str = urlread(fullURL);
>> whos str
Name Size Bytes Class Attributes
str 1x82552 165104 char
Has anyone else had this issue? It use to work just fine for me a few months ago. I wonder if it is some internet setting issue.

Thanks for your response Geoff. This magically started working and I haven't been able to reproduce the problem.
