Web app won't open

[City_ofLangley]

Hi

It seems I cannot access the web app I've been working on. It was working just fine for me last week, but when I tried to view and edit it this morning it gave me this error message: "Item does not exist or is inaccessible." I also attached a screenshot of the error message below. I'm not sure what I'm doing wrong but I still can view my older web apps. Any help would be appreciated.

Is this WAB Dev, AGOL or Portal version?

Hi! I'm not sure in all honesty. I'm very new to GIS still. I don't know if it will help, but I attached a screenshot of it from ArcGIS online.

OK, then that is the AGOL version. You best bet is to call esri tech support as there is little we can advise in your situation.

City of Langley,

Did you ever find a solution to this issue? I am running into the same problem. All web apps in my Portal for ArcGIS are throwing a "Item does not exist or is inaccessible" error. Their subsequent Web Maps are working properly.

Thanks,

Cherie
