First of all, check the network access of that report server, if working then check the URL in report manager of report server by using http://localhost/reports.
if it works fine, please try to add <identity impersonate="true" username="user1" password="password"/> in your application web.config file. make sure that user1(which could be any account) is the system user in both report server and web server. give
the read/browse rights of this user in report server.
