Static IP Error?

I think this might be an admin UI bug?

see this. You have to manually specify a useable subnet outside of /24 then you can go back and set that...

Static IP Address and DHCP Support for non /24 Subnets

There's a direct endpoint without /24 limitation for those who know what they are doing. The endpoint is /hub/advanced/switchToStaticIp, and it accepts the following query string parameters (names are self-descriptive): address netmask <- use 255.255.254.0 for /23 subnet. gateway nameserver

Looks like they added support for the /23 to the UI since that 2021 post though, but the rule to make sure you don't do something really stupid seems to be tied to a /24 subnet still.

So yes, looks like a bug, you can use the endpoint in that other post to force it whatever you want (even if invalid).

Personally, I would just set the IP on the router DHCP and leave the hub on DHCP.

If you are not sure how to build the query string, I think this should work

http://HUB.IP/hub/advanced/switchToStaticIp?address=10.0.1.131&netmask=255.255.254.0&gateway=10.0.0.1&nameserver=8.8.4.4%2C8.8.8.8
