We have aspx page where is added Telerik ReportViewer element:
In cs file we set stuff to that report viewer:
Problem is that from our own test environment we can run reports properly. Customer get vpn connection to our network and can run reports from same environment properly.
Customer has virtual server in azure cloud enviroment where currently is only allowed our and customer connections. From there we can run reports properly, but when customer try to use that page from their network, it will wait long (about minute) and get only toolbar of ReportViewer, no parameters area above that toolbar or any information about db connection problems or something else below.
Any idea where problem could be?
