Error fetching http headers in SoapClient

Question

I\'m trying to invoke a WS over https on a remote host:remote port and I get:

Error fetching http headers

using the PHP5 SoapCli

Answer 1

I got this same error and in my case the server I was sending the request to was replying with a 504 Gateway Time-out error. I didn't realize this until I went to the URL in a browser that was being requested by the SOAP request:

eg. https://soap-request-domain-here.com/path/to/file.wsdl
