Unable to bind WSDL due to IIS returning a port number

Question

Unable to download the following files from http://website/WebService/service.asmx?wsdl, http://website:84/WebService/service.asmx?wsdl. Do you want to skip these files and continue?

When the url: http://website/WebService/service.asmx?wsdl is used on IE/Chrome the response is correct?

Any help is highly appreciated
