Netwatch and disable interfaces. Or what am I doing wrong?

Good afternoon! Connoisseurs, tell me, can netwatch make interfaces inactive?

I have a 4G modem SXTLTE3-7. Recently, a sad strangeness has appeared, there is a connection with the opsos, but the traffic does not go :(

If you make the lte1 interface inactive, and then activate it again, the modem connects and everything starts working again.

A simple script:

/interface lte set lte1 disable=yes
/interface lte set lte1 disable=no

when manually testing it worked, but when I put it on netwatch Down, it does not work.
Tried to set a delay, but nothing has changed.

Tell me where to dig.

Thank you!

You can try to update the modem firmware:
/interface lte firmware-upgrade lte1 upgrade=yes
And how to update it say:
/interface lte at-chat lte1 input="AT+reset"

There is a guess, I'm not a telepath.
Probably the modem works in NAT mode, and netwatch checks the availability of the GW provider (pings), which in your case is the modem. That is, mikrotik pings the modem, in case of a problem, the modem loses its radio connection with the mobile operator, but this does not affect the ping in any way. Accordingly, netwatch does not know about the problem with the Internet channel.
It is necessary to ping some resource on the Internet to check the operation of the Internet channel.
