After upgrading omada controller to v5.3.1, I got firmware update notice. As I do not see any release notes on this forum, I'll post screenshots of changes:

At present, only the new firmware releases for Omada SDN Controller and Omada Gateway are actively updated on this forum. Due to the variety of the EAP product line, it's hard to do the same for Omada EAP products on the forum. However, the controller will push the new firmware release instead to notify you of the update available.

After rebooting all devices in local network, I retried upgrade to v1.0.4 but it failed again. I clicked then on blue button about rolling firmware and got this:

The above error message indicates that the firmware downloading was failed, which might be caused by the network fluctuation. To verify the issue, more detailed information is required. Are you willing to help us with further investigation?
