Hello - I have several Web reports in my application.  They work wonderfully... most of the time.  Every now and then, a Report will just spin and spin and spin, never actually displaying the Report.  If I go back and rerun the Report, it generates immediatly (as it should).  I'm not sure what to trouble shoot here, since clearly it works 90% of the time.  One user let it run over night and in the morning, it said 'Page Not Found'.  Do you have any suggestions?

Hi TPerry,

You're the first one to report such a problem and if the problem is really reproducible in 10% of the time, it would be best if you open a support ticket and provide us with a runnable sample project so we can try to replicate it locally and advise you on how to proceed.

Best wishes,
Steve

My apologies for taking so long to get back to this.  When the application is run in the same office as the SQL and Web servers, it doesn't happen.  However, if a user in a remote office or at home via vpn tries to run the report, that's when the report will hang.  And in my case, that is 99% of the users.  Is there something I can investigate regarding it timing out or dropping a connection?  Because as soon as the user clicks Back and reruns the report, it appears quickly.

Hi TPerry,

According to your description it seems that this issue is somehow related to the VPN connection. Please use the Fiddler tool to investigate the responses to the page with the viewer, especially the one with the following signature: http://...Telerik.ReportViewer.axd?culture=en-US&uiculture=en-US&instanceid=f32ff1357e8f43d28428b32188aae0bb&optype=Report&PageIndex=0

You can check the raw response on the right side -> Inspectors tab -> Raw button. Hope this helps.

Again, I apologize for not getting back to this sooner.  I tried Fiddler, but to be honest, I don't really understand what I'm loking at.  Today, I am working from home, via vpn, and I pulled up a Report that has 4 pages.  Pages 1 and 2 displayed immediatly.  Though, when I try to view page 3, it just spins and spins.

Here is what I get when I click on the last Fiddler entry for this app.  The little icon in the first column is a green down arrow and there is no result in the result column.  Now, the funny part is that, before I got the Fiddler results that are below, I tried the Report and pages 1, 2, and 3 rendered quickly, but page 4 spun and spun.  And then I just tried it again and page 1 rendered quickly and it got stuck on page 2.  So, you can see how frustrating this is for me (and the users).

If you have any suggestins or thoughts, please help!

GET /Telerik.ReportViewer.axd?culture=en-US&uiculture=en-US&instanceid=89370a0940f3457fa4cc7c596b2d1ac4&optype=Report&PageIndex=2 HTTP/1.1

Hi TPerry,

Only Fiddler can give us any clue about the problem. You have sent the GET request for the page but what should be checked is the Response for it. Please, see the attached screenshot. Check the Result column for the request on the left and the Raw response on the right. You can also save the http session into an archive and send it to us in a support ticket (in forum threads attachments are not allowed).

Sincerely yours,
Chavdar

The problem with the Raw data, is that since the page never loads, there's no data in that section.  There is no number in the Result column and the image remains a green down arrow.  I have provided 2 links to screen shots.  The one called fiddlersuccess.gif is a screen shot of the first page of the Report which loads correctly and quickly.  The second link is a screen shot called fiddlerfailure.gif, which is the page of the report that doesn't load at all.

Any help would be appreciated.  Thanks!

Hi TPerry,

This information is insufficient to determine the reason for the problem. If the server had returned some kind of error to indicate a possible problem with the Reporting tool we would have been able to research and probably fix it. However, these screenshots just indicate that the browser is waiting for a response which is never received so there is not way to know what is happening. The only suggestion I can give is to upgrade to the latest version of the product in which is the response output is buffered. However, there is a little chance that this would solve the problem.
