Deplyment worked great first time - now just errors.

MsDeploy seemed to work flawlessly for me the first time I attempted to publish. In fact, my site is up and everything.

But now, whenever attempting to publish again, I'm getting the following:

Error 1 VsMsdeploy failed.(Remote agent (URL https://netfx4lab.discountasp.net:8172/msdeploy.axd?site=user166.netfx4lab.discountasp.net) could not be contacted. Make sure the remote agent service is installed and started on the target computer.)

An unsupported response was received. The response header 'MSDeploy.Response' was '' but 'v1' was expected.

P.S, By the way, FTP seems to work fine.

 

Now getting the following:

Error 1 VsMsdeploy failed.((12/8/2009 9:26:43 AM) An error occurred when the request was processed on the remote computer.)

Idumond --
I got a message like yours until I checked the checkbox "Allow Untrusted Certificate". Only then was I able to publish successfully.

 

I have "allow untrusted certificate" checked. If I didn't it wouldn't even be getting as far as it is before failing, since the sandbox server doesn't have a valid certificate installed.

Please note, the error I'm getting has nothing to do with SSL.
