Can't update ER605
I'm trying to update my ER605 with firmware 2.2.4 and it keeps failing with this message:
[Failed]Failed to upgrade 50-91-E3-44-05-26 to firmware version 2.2.3 Build 20231201 Rel.32918 online. Please check your network configuration and make sure the device can access the Controller's HTTPS management port.
First, the error message seems to indicate that it's attempting to upgrade to the firmware version it's already running, unless I'm misinterpreting. Regarding the rest of the message: the HTTPS management port of the OC200 is 443, which I think is correct. My configuration is simple: an ER605 with an active WAN connection connected via LAN to a POE switch, with the OC200 and a laptop also connected via wired. What do I need to do to enable the ER605 to access the OC200?
I've already tried downloading the firmware and doing a manual update. It gives the same error.
