Zyxel Keenetic 4G II. How to fix the error: Process: "Resolver" has been killed?

Question

Yota

The Zyxel Keenetic 4G II router in conjunction with the Megafon M150-1 modem (with a Yota SIM card) periodically gives an error Process: "Resolver" has been killed.
After that, Internet access disappears and it can only be fixed by reconnecting the modem to the router. How can I solve this problem (except for the iota there are no more options for connecting to the Internet)?

Answer 1

I did it with shamanism:
- factory reset
- updated the firmware to the beta release: v2.04(AAKW.1)B3
- indicated google dns: 8.8.8.8
Of course, I messed up all sorts of left-handed applications like: YandexDNS, Netfriend and others like them.
The error magically disappeared.
PS This is indeed shamanism, it is quite possible that this did not help either.
