Question

How can the error 'Client found response content type of 'text/html'.. be interpreted.

Answer 1

+2 A:

That means that your consumer is expecting XML from the webservice but the webservice, as your error shows, returns HTML because it's failing due to a timeout.

So you need to talk to the remote webservice provider to let them know it's failing and take corrective action. Unless you are the provider of the webservice in which case you should catch the exceptions and return XML telling the consumer which error occurred (the 'remote provider' should probably do that as well).

I wrote the webservice. I'm catching all exceptions on the server, but don't get any. I get this timeout message appearing at the client end before the method on the server end returns.

@VinkoVrsalovic: Thanks earlier. It's been closed again! I can't help but laugh now though. :)

Thanks for your answer though. I guess there must be something going on in the middle that I don't understand.

Are you sure you are catching HttpExceptions?

Answer 2

+1 A:

This is happening because there is an unhandled exception in your Web service, and the .NET runtime is spitting out its HTML yellow screen of death server error/exception dump page, instead of XML.

Since the consumer of your Web service was expecting a text/xml header and instead got text/html, it throws that error.

You should address the cause of your timeouts (perhaps a lengthy SQL query?).

Also, checkout this blog post on Jeff Atwood's blog that explains implementing a global unhandled exception handler and using SOAP exceptions.

Answer 3

A:

The webserver is returning an http 500 error code. These errors generally happen when an exception in thrown on the webserver and there's no logic to catch it so it spits out an http 500 error. You can usually resolve the problem by placing try-catch blocks in your code.

Answer 4

A:

Is your webservice configured correctly in IIS? The pool its using, the version of ASP.NET (2.0) is set? Can you browse the .asmx?

Talking about exceptions, try to put an try-catch block in the line that access your webservice. Put and catch(System.Web.Services.Protocolos.SoapException).

Also, you can set a Timeout for your webservice object.

@Gustavo: StackOverflow has just turned one year old! The question you just answered is almost that old. Also, if you read the entire question and all the answers, you'll see that there's no way to catch this on the client, since it never gets to the client. I'm going to have to give you a downvote because your answer is not helpful. I hope this does not discourage you from trying to help.
