Check for updates error

Thu Jun 16, 2022 3:13 pm

Hi,
i just found, that update checking is corrupted. DNS resolve for upgrade.mikrotik.com is 10.0.0.6.
It´s not a local dns problem...mxtoolbox also resolve this IP as well.

I can confirm this. Futher investigation turns out, that mimas.mt.lv is responding with the wrong NS record:
Code: Select all

Temp fix, please check the legitimacy of the IPs by any means
Code: Select all
/ip dns static
add address=159.148.172.226 name=upgrade.mikrotik.com
add address=159.148.147.204 name=upgrade.mikrotik.com
add address=2a02:610:7501:4000::226 name=upgrade.mikrotik.com type=AAAA
add address=2a02:610:7501:1000::204 name=upgrade.mikrotik.com type=AAAA
The AAAA records are useless since the upgrade system isn't IPv6 capable yet.
