Failed to fetch error

[William Cowan]

I get the following error on several manifest files:

{
"manifest": {
"error": "TypeError: Failed to fetch",
"id": "https://pages.dlib.indiana.edu/concern/scanned_resources/dz890s432k/manifest?manifest=/concern/scanned_resources/dz890s432k/manifest",
"isFetching": false
},
"window": {
"collectionIndex": 0,
"companionAreaOpen": true,
"companionWindowIds": [

"cw-bfcc19c3-3e6b-44c7-96cf-c30c36ecffdb"
],
"draggingEnabled": true,
"highlightAllAnnotations": false,
"id": "window-692158ee-7dcf-4ad8-b4e9-a1398c0f18c5",
"manifestId": "https://pages.dlib.indiana.edu/concern/scanned_resources/dz890s432k/manifest?manifest=/concern/scanned_resources/dz890s432k/manifest",
"maximized": false,
"rangeId": null,
"rotation": null,
"selectedAnnotations": {},
"sideBarOpen": false,
"sideBarPanel": "info",
"thumbnailNavigationId": "cw-bfcc19c3-3e6b-44c7-96cf-c30c36ecffdb",
"loadedManifest": "https://pages.dlib.indiana.edu/concern/scanned_resources/dz890s432k/manifest?manifest=/concern/scanned_resources/dz890s432k/manifest"
}
}

When I click on the link in Omeka-s the manifest file displays in the web browser so I am not sure what I should be looking for.

thanks for any help,

Will
