For our initial implementation of UltiDev Webserver Pro, we were successful with one PC, but unsuccessful with another PC that is behind a more restrictive PC firewall.

Messages received by the PC which cannot run UltiDev are: IE cannot display webpage, Oops Google Chrome could not connect to localhost:8080, & Firefox cannot establish a connection to a server at localhost:8080.

netstat –o does not show anything running on localhost:8080 for the PC behind the PC firewall.

What in our PC firewall could be blocking access to localhost:8080?

Hi, Amy.

If you run netstat on the PC where UWS is installed, and it does not show your application port taken, then it's probably not a firewall problem. It could be either application not registered properly, or UWS not running.

If you could, please attach a screenshot of the UWS Explorer with your application selected - we may be able help if something is not registered correctly.

Amy,

From the screenshot it looks like the URL you should try is http://localhost:8080/NobleWebReports/ instead of http://localhost:8080/. Your application is registered with a virtual folder named "NobleWebReports".

this is a folder that we created during the install of our noble software that leverages utildev to create the reports.

Hi,

Have you tried to reach the application at http://localhost:8080/NobleWebReports/? Does it work? If so, is this something you can work with, or do you need the URL to be different?

Actually, we have always used http://localhost:8080/NobleWebReports/ to connect(Screenshot attached.) I first referred to http://localhost:8080/ to generalize the issue; however, it obviously mislead you. Sorry.
Our Engineer has observed that when NobleWebReports application failed to run, some Ultidev services had red indicators on UWS Explorer screen, meaning as we see it that they weren't running. Can you pursue this further with us?

Hi, Amy.

Do we understand you correctly, that your web application sometimes runs and sometimes is down? Or is it always down?

If you could attach a screenshot with UWS Explorer showing red marks, it might be helpful for us to understand what's going on.

Please also consider right-clicking on the folder with the application and running it under UWS interactive host, as shown on the attached screenshot: that shows request trace, and may provide useful error information.

Best regards,
UltiDev Team.

Received this error trying to start running our application under UWS interactive host on PC that always fails to run it. "Failed to listen on prefix 'http://127.0.0.1:27520/' because it conflicts with an existing registration on the machine."
Attached trace display, netstat -an, & Task Manager processes.

Amy,

Could you please run the following command in command window:
Code:
netsh http show urlacl >> c:\httpsysreg.txt

twice: once while UWC Interactive is running (and app is failing to listen) and second time when it's not. Please attach c:\httpsysreg.txt to your reply for us to look at.

These two files do not appear to be generated while following our instructions.

Here's what we would need in order to help troubleshooting this problem. On the box where you get "Failed to listen on prefix 'http://127.0.0.1:27520/' because it conflicts with an existing registration on the machine." error, please do
Code:
- Right-click on the folder with the application and run it under UWS interactive host.
- Run netsh http show urlacl > "c:\httpsysreg listenting.txt"
- Exit UWS interactive host running the application.
- Run netsh http show urlacl > "c:\httpsysreg non listenting.txt"
- Please attach both "c:\httpsysreg listenting.txt" and "c:\httpsysreg non listenting.txt" to your reply.

UltiDev Team.

Thanks, Amy.

Assuming you are still getting the conflict error message when accessing your application at http://localhost:62353/NobleWebReports/, we can only tell that http.sys driver application registry shows no conflicts. This error is quite specific, and orphaned http.sys application registrations tend to be the only reason for the error, but it does not appear your system has orphaned http.sys URL registration entries. Unfortunately, we cannot tell what is going on. We didn't have this problem reported by other users either. Please let us know if you have a theory of your own.

We wonder if all UltiDev services are running when needed.
What UltiDev services should be autostarted when Windows 7 starts up?
We launch UltiDev from a client-server application (Noble Systems Corp Maestro). When we select the option to run our app NobleWebReports from the Maestro GUI, would it have to launch other UltiDev services? If so, what are they?

Amy,

The need to start UWS depends on whether you have registered your web application with UWS Windows service, in which case UWS does not need to be started manually, or whether you run UWS in the interactive mode, in which case you need to need to start it as an application with command line parameters.

Service mode: On the machine where your web app is hosted, please run "UltiDev Web App Explorer" from UWS start menu to see which applications are registered with UWS service. You will see something like this. Green icons next to web applications and host processes mean they are up and running. Red icons mean host process or application are not running and may need to be restarted. After you select and application, you can use "Browse Application" button to launch a web browser to see the application running on the machine. If you see no registered applications in UWS Explorer, go to http://localhost:7756/ - it shows a simple diagnostic web application hosted by UWS but not displayed among registered ones. If that application is accessible, then UWS is installed and running correctly.

Interactive UWS host, running as a regualar application, has multiple command line parameters that make it possible to specify application path and many other things, like, for example, whether to start a web browser along with the host.

Please let us know if this information was helpful.

UltiDev Team.

Our app NobleWebReports appeared in Web Application Manager.
Icons for hosts UltiDev Web Server App Director & NobleWebReports were green.
Icon for app NobleWebReports was green.
When clicked "Browse Application" for NobleWebReports, received the error that we always receive: "Internet Explorer cannot display the web page".

Amy,

Were you able to hit http://localhost:7756/ URL on the same machine? It would tell us if the problem is with UWS server as whole, or just with your application.
