MATLAB: What happened with KEGG

Hi I'm trying to connect to KEGG with

wsdlURL = 'http://soap.genome.jp/KEGG.wsdl'; className = createClassFromWsdl(wsdlURL);

commands, but get error

Error using urlread (line 111) Error downloading URL. Your network connection may be down or your proxy settings improperly configured.

Error in createClassFromWsdl>parseWsdl (line 54) downloadedData = urlread(wsdl);

Error in createClassFromWsdl (line 32) [R, schema] = parseWsdl(wsdlUrl);

No proxies, url works fine with other addresses.

Any ideas?

Thanks
