Incident description

Screenshare not working in Chrome browser in spite of having the correct Chrome-Extension installed

Resolution description

Check current installation

  • Check if the correct chrome extension is installed, which can be obtained from here
  • Check if the correct chrome extension-id is configured on you talk-server installation:

--> log into your zimbra-talk-server's command line via ssh and execute these commands, which display the configured extension-ID for the Chrome-extension: --> execute:

sudo cat /etc/zimbra-talk/talk.defaults.cfg | grep "CHROME_EXTENSION_ID" 

answer:

CHROME_EXTENSION_ID = <currently configured ID>

--> execute:

sudo cat /etc/jitsi/meet/zimbra-talk-config.js | grep "desktopSharingChromeExtId" 

answer:

desktopSharingChromeExtId: '<currently configured ID>', // Id of desktop streamer Chrome extension

For both commands it must return kdngbjobgegkbbifbijhmphjdibndnfp as <currently configured ID>.

Replace wrong Chrome extension-ID

In case of for <currently configured ID> is something else returned then kdngbjobgegkbbifbijhmphjdibndnfp, it must be corrected. This is done by performing these comands on the talk server's command line:

  • Create a backup of you config files:
sudo cp /etc/zimbra-talk/talk.defaults.cfg /etc/zimbra-talk/talk.defaults.cfg.sav
sudo cp /etc/jitsi/meet/zimbra-talk-config.js /etc/jitsi/meet/zimbra-talk-config.js.sav

Replace the wrong extension-ID by the correct one in both files:

sudo sed -i -r 's/<currently configured ID>/kdngbjobgegkbbifbijhmphjdibndnfp/g' /etc/zimbra-talk/talk.defaults.cfg
sudo sed -i -r 's/<currently configured ID>/kdngbjobgegkbbifbijhmphjdibndnfp/g' /etc/jitsi/meet/zimbra-talk-config.js

Note: Replace <currently configured ID> by the actual extension-ID displayed in 2.

After reloading your browser-window via CTRL+R or Shift+Reload screensharing should work now.

Symptoms

In spite of having the correct Chrome-Extension installed, when activation Share Screen, this error message is displayed:
