Connection error in cesium ion story

I have been encountering no connection retrying error, also assets added to the story are not been updated because of the connection error. Please any suggestion on what to do.

This error typically occurs when there is a problem with the network connection. It normally goes away when the network connection is restored.

If you are able to provide some additional information that will help us investigate more:

  • Are you able to access other sites when this happens?
  • Are you able to load when this happens?
  • Are you still experiencing this issue?
  • If you are able to access the developer console, can you provide any error messages there?
  1. I can load other sites and when this happens.

When this happens, I’m able to access other sites, and also load cesium ion. This problem has been persisting for over several weeks now.
This are the error messages from the developer tools : error 404

{"code":"InvalidCredentials","message":"Invalid access token"}

Access to XMLHttpRequest at ‘’ from origin ‘’ has been blocked by CORS policy: Method PATCH is not allowed by Access-Control-Allow-Methods in preflight response.

Does this error still if you reload the stories page? If you have left the stories page open for a long time, it is possible that the access token expired.

Yes, the error persists even after reloading the page.

Thank you for that additional information and your patience while we investigate. We are still trying to reproduce this. We have some additional questions. Thank you.

  • Does this issue happen on all your stories or just a single story?
  • Can you walk us through step by step what edits you made to the story when this error happens?
  • Are you able to have a share a story with just one slide that illustrates this issue?
