[Satellite6] synchronizing >800 repos to a Capsule fails with connection errors

Issue

• having over 800 repositories in a Lifecycle Environment (L.E.)
• trying to synchronize a Capsule assigned to that L.E. fails - expected error code is either:
  • wrong status line: "CONNECT capsule01.example.com:443 HTTP/1.1" (Net::HTTPBadResponse)
  • Server broke connection (RestClient::ServerBrokeConnection)
