Updated over a week ago

A host or a guest might see a blank or loading page when trying to access Zencastr.

In this article:


The host or a guest sees a blank/white screen when opening a Zencastr page.

Or, the host or a guest sees the message “Zencastr Loading. Thank you for your patience.” for several minutes without any apparent progress.


Zencastr is a large application and has system requirements in order to access it.

A blank page or page stuck on loading can happen when:

  • Host or guest has a slow or unstable internet connection.

  • Host or guest tries to access Zencastr from a computer or browser that doesn’t meet the system requirements or from an unsupported mobile device.

  • Host or guest has browser security extensions installed that block Zencastr.

  • Host or guest has an ad or script blocker installed that blocks Zencastr.

  • Host or guest is connecting from a network that has strict security settings (e.g. a company, university, hotel) that blocks Zencastr.


The person encountering the issue, host or guest, should try in this order:

1. Verify that Zencastr is being accessed from a computer (not a mobile device such as a tablet or smartphone) and browser that meets the Zencastr system requirements.

2. Refresh the page.

3. Clear the browser’s cookies and cache for Zencastr.

⚠️ If the host or guest has any unfinalized tracks for a previous recording, any backups of that person's files that exist in the local browser storage will be deleted upon clearing cookies and cache. It is recommended to do troubleshooting for any unfinalized tracks first, if possible.
