Portal, "The layer could not be loaded"

I recently used ArcGIS online assistant to move a map over from AGOL to Portal. 

I am receiving the following error and it is very annoying- 

"The layer could not be loaded." The thing is, I can see all of the layers that should be there. What Layer? "The" Layer? What does that mean?

I would look into using Admin Tools for ArcGIS Online for this task.

You can also run the dev tools or Fiddler when opening the map to see which request/service/layer is failing to load. That should help narrow down which is the problem.

I am having this issue as well in a web map. "This layer could not be loaded." No specific layer is referenced, and it pops up VERY frequently. I need to turn it off 14 times before I can continue, and the cycle repeats often.

The thing is, all layers are loaded.

I have saved the map that gives me this message. Normally, when I get this message, the layer does not load at all, and if I were to save the map, it would save without this layer loaded into it and I would not continue to get this message.

Any idea what's going on here? Something seems to be broken.

Thank you,

We had the same issue and I believe I got to the bottom of it. It boils down to the itemid of the layers in the webmap not referencing an item in Portal. I suspect when you copy a webmap in AGOL Assistant from one Portal / AGOL to another and change the URLs only the URLs are changing but the itemid of the Map Image Layer for instance are not. The layers still load because they have the correct URL but the error message pops up because the itemid doesn't exist in your portal. The only solution I could see was to use AGOL Assistant to manually change the itemid to match the itemid of the layer in your portal.
