Screen Sharing Troubleshooting

Last updated

Error Message - "Could not start screen share"

If you are seeing the above error message, it could mean a few things. Either the request was cancelled or your browser doesn't have permission to access screen sharing.

Windows Permissions: Currently, Windows doesn't have any system-level permissions for screen access. If you're running into problems or getting an error, double-check your browser settings.

Chrome and Chromium: Currently, Chrome doesn't have any specific settings related to screen access.

Updating Safari Permissions

It is possible that screen sharing was accidentally blocked at a browser level. In Safari you can fix that with the following:

  1. In your menu bar, select Safari->Settings
  2. Select the Websites option
  3. Scroll down to the Screen Sharing section
  4. Find your website and verify it is set to Ask

Updating macOS Permissions

In more recent versions of macOS, Apple has introduced system level permissions for applications, like your browser, to access screen sharing.

To update these settings, take the following steps:

  1. Open up System Settings on your Mac
  2. Click on the Privacy & Security section
  3. Scroll to the Screen & System Audio Recording section, and ensure that your browser is toggled on
  4. Restart your browser

Updating Firefox Permissions

When using screen sharing in Firefox, you'll see a pop up that asks if you'd like to allow Adracare to access your screen


If Always block was accidentally selected, Firefox won't show this prompt again. In this case, you'll need to manually reset the permissions for screen access by doing the following:

  1. Click on the Site information area, just to the left of the website address
  2. Locate the Share the Screen item in the list, and select the "X" next to Blocked



  3. Refresh the tab

Shared Screen is Difficult to Read

If you're having trouble reading smaller text on a screen share, try making the window or content that is being shared smaller. That might mean instead of sharing the entire screen, share a browser window/tab that has been resized slightly. Or, if you have a large monitor try to not use an app window or browser tab that is stretched to the full size of the monitor.
