I am having issue loading Device page on IoT Central. I need to get to this device page to get the connection string/key information. Spinning wheel keeps spinning and page doesn't load. I tried different browsers (Chrome, Firefox & Edge). None of them work. All other pages load properly.

@RoopakIngole-9169 To understand your issue better, was it working earlier? Since how long you are experiencing this issue?
Are you using Legacy Application?
Hello Ashok,
Yes it was working earlier. I was able to get to the devices. Since yesterday I am not able see it.
I will try restarting my machine/browsers.
As far as Application template, I am really not sure. The application was created by our Subscription Admin and handed over to us. From the Application itself, is there any way I can confirm this ?
Thanks Satish.
I will try it on different machine. My application is deployed in USA region.
I have tried different browsers, still the same issue.
I can try restarting my machine and check.
FYI: Attached is the snapshot what I get whenever I click on Device.
Hello @Roopak Ingole , Please visit the document on Get information about your application page, you can find out if your app is legacy or not.
Please don't share any sensitive info related to you App on public forums, always Mask the sensitive info while sharing app info or images on public forums.
Hello Satish,
Template says iotc-pnp-preview @ 1.0.0
which i assume is not Legacy.
Is this info helpful?
@Roopak Ingole If app version=2 it is a legacy app, if version=3, it is latest. I tried multiple times but unable to reproduce your issue. I can see the devices page without any problem in my application.
Can you please try again now by following all the above suggested troubleshooting steps and report back?

@RoopakIngole-9169 These are good troubleshooting steps, if these dont work then please provide your application ID or the URL that you are trying to load and I will take a look on our side.
I went through the troubleshooting steps.
Only thing worked was opening up the iotcentral on another laptop. This tells me that there must be something on my machine that is blocking to open up the device pop-up. I made sure that I disabled adblocker and pop-up blocker.
how can I send you @AshokPeddakotla-MSFT private message with my application ID?

Hello,
Is your problem resolved? We are also facing the same issue, not able to see devices under devices page, getting an error message saying
Error
Something went wrong
Error Code: 500.011.998.016 / 16m3ochzsth.1
I just started exploring IOT Central and started seeing this issue and couldn't go furthur of adding devices because of this issue. One of my other team mate also tried this in his machine by creating new custom application but still the same. He is also getting the same error. I tried for Custom application, in store analytics template, but having same problem and yes i tried US and Europe regions. Please let me know if there is any solution.
Thanks,
Nandini
This error is the result of the browser failing to fetch from the back end. Our Product team is working on providing a fix/update for a more graceful & cleaner error message when the client appears to be offline or a fetch API call fails.
Meanwhile, suggest you to double check your network connection, as well as any firewalls that could be blocking the requests.
