Apple - Clicking on external links opens Chrome but not the link
I had this happening all afternoon. Then I checked Chrome | About Chrome and it was waiting for me to relaunch to update. That fixed it.
Try entering chrome://restart
in url line and hit enter.
This will fully restart Chrome and all of it's children processes including Chrome-based apps.
I assume it's not the Update which helped others here, but the Chrome restart.
Updating Chrome solved the issue for me.
NOTE: The problem can reproduce each time a new version of Chrome is available...
