Gl-xe300 lts modem restarts every 4 minutes

Hello,

I recently purchased a gl-xe300. I am having trouble with the lte modem reliability; it appears to be restarting every 4 minutes which is interrupting access forwarding provided by soracom.

using firmware v4.0
router is connected via the EG25-G modem with provider 'soracom', my computer is connected via wifi or lan cable

here is several lines from logread that show the modem going offline/online every 4 minutes:

...why is ifdown being run automatically?

Try to disable the Interface Tracking Status in the Failover settings.

how do i do that? can i do it in the glinet interface? or do i need to use luci?

I cant seem to edit the modem interface, unsupported protocol type, and trying to edit the virtual interface associated with the modem that actually has an IP address results in

TypeError
Cannot read properties of null (reading '.name')

All within the GL interface.

found it. will try and report back.

well its been up for 30 minutes and i dont see the Execute ifdown

Soracom does not support ipv6, but it looks like mwan is configured to use ipv6

/etc/config/mwan has the following for my modem:

config interface 'modem_1_1_2_6'
        option enabled '1'
        option family 'ipv6'
        option reliability '1'
        option count '1'
        option timeout '2'
        option interval '5'
        option down '3'
        option up '8'
        list track_ip '2001:4860:4860::8844'
        list track_ip '2001:4860:4860::8888'
        list track_ip '2620:0:ccd::2'
        list track_ip '2620:0:ccc::2'

how do i disable ipv6? I already had attempted to do so:

why does /etc/config/mwan show ipv6 addresses for the track_ips even when the tracking was configured with ipv4 addresses?
