Request Failed: Unable to connect to remote server

Question

I've seen several people post this error, but none of the suggested solutions have resolved my issue. This seems very simple to me, so I'm sure I am missing something very basic. I am very new to using Visual Studio for testing, so please bare with me.

I have a local ASP.NET 2.0 application that strictly uses Windows security. I have recorded a very basic web test that navigates to one page within my application and that is all. When I run the test, I get a "Request Failed: Unable to connect to remote server" error. I have verified that the proxy setting is blank. I've recorded several other tests against .aspx pages and .htm pages with the same results.

I am using the following version of Visual Studio.

Microsoft Visual Studio 2005
Version 8.0.50727.42  (RTM.050727-4200)

Microsoft .NET Framework
Version 2.0.50727

Installed Edition: Enterprise - 77718-007-4000003-41135

Answer 1

This error usually occurs when you are trying to hit a page that needs the proxy property to be set.  I see you said that it is blank.  Are your internet settings in Internet Explorer using a proxy?

Answer 2

No. I do not use a proxy. My IE settings are set to "Automatically Detect Settings". The page I am trying to hit a from a web app on my local machine.

Answer 3

Is your test going against a web site deployed to IIS or to a website using the development web server,cassini?

Answer 4

I am testing against a published web application on my local machine. Published to IIS.

Answer 5

David,

Can you disable proxy detection and verify you can hit the page(s) in IE?

Answer 6

I assume when you say disable proxy detection, you mean uncheck "Automatically Detect Settings" under IE settings. If so, I get the same results when automatically detecting settings just as I do when leaving the box unchecked. In both cases, I can hit the local app or any other Internet site when just using IE; however, when I attempt to run a web test against the local app, I get the same failure.

Answer 7

Is this error from just running a webtest in playback or is this from running this webtest in a loadtest?

Answer 8

For now, it is playback only.

Answer 9

Are you running some sort of firewall/proxy client such as MS ISA Firewall Client?

Answer 10

I was dealing with this error for days and had done everything that was supposed in several fora. Without success. Finally (just before re-installing my machine completely) I solved it by removing old Visual Studio parts (beta's) and an inactive(!) firewall program.

I seem to get this error from playing back through a website. Even when I am trying to run a webtest I get unable to connect to remote server.
