The polling url does not start with https despite the login url started with https

Hi,
I found a solution after digging a lot on internet.
Following changes solve the problem.

  'trusted_domains' => 
  array (
    0 => 'domain.ltd',
  ),

  'overwrite.cli.url' => 'https://domain.ltd',
  'overwriteprotocol' => 'https',

NC works as expected now on k3s cluster.
