First, what happens when you connect to the URL directly to the WSDL file in a browser?
Second take a copy of the WSDL file directly and use that to create your consumer does it then work?
Normally the WSDL is used to create the script library and not used after that (in that it shouldn’t make a further URL call). So it is a little unclear why your consumer is saying that message.
I have also this problem. However I am running 8.5.2 FP1. I have not tried in 8.5.1 but I might try if it will import my wsdl-file correctly.
My wsdl-file is 1,3 MB in size and is the Web Service of Microsoft Dynamics CRM.
When I try to import it as a file from my local machine I get error “The requested operation failed: WSDL2 emitter timed out (content too large to handle)”.
When I try to import the wsdl from a URL I get error “No WSDL was returned from the URL: http://myurladdress.wsdl”
I experienced a similar problem with version 8.5.3 FP3.
I could not retrieve the WSDL from a local server or any publicly available WSDL on the internet. It was a simple matter of the proxy server in my location document was incorrect set which prevented any URL request from being processed within the Notes client.
In my case, I removed the proxy server setting and the Web Service Consumer request worked.
Hope this may helps someone who runs into this issue.
