Problem with deploying report project from VS.NET

When I try to deploy my report project from vs.net i got the following message:
"A connection could not be made to the report server https://rs.discountasp.net/reportserver".

I think that TargetServerURL and TargetFolder are OK.

My developing computer (VS.NET, SQL 2000 Developer, Reporting Services) is on SBS2003 domain which uses proxy server.

I also had a problem with registering web references (https://rs.discountasp.net/reportserver/reporservice.asmx), but i solved it by setting proxy exceptionsto https://rs.discountasp.net(Do not use proxy server for addresses beginning with in Internet Options, Connections, LAN Settings, Advanced), but it didn't help with my deployment problem.

Deploying on my http://localhost/reportserver works fine, and deploying on https://rs.discountasp.net/reportserver from other computer which is not part of network also works ok.

Any help would be appreciated.

 

Connection and upload works through ReportManager (but also not too good, I can upload rdl and rds files, but shared datasource is not "bound" to report, so I have to manually set datasource for each particular report).

I have tried to override proxy settings like I did describe in previous post, but it didn't help.
