The above error message indicates that the switch is unable to access the Controller's HTTPS management port, please confirm the required port is open. For more detailed suggestion, please refer to the following solution post,

Kind note that both the 1.1.4 and 1.1.5 firmware are adapted to Controller v5, while Omada Controller v5 has changed the port for firmware upgrade. When there is a NAT device or Firewall existed between your switch and controller, you may suffer from this issue of upgrade failure.
