Check updates fail / dns error after automatic upgrade to 6.47.2

Hi guys,

I have a strange issue: I have 3 routes:

main router (4011) has dns and dhcp settings
one audience, work as access point
one more router as wireless bridge

after upgrade to 6.47.2 on the audience I cannot check for further updates anymore - “dns is not resolved” error

the funny thing as it works just fine on the main router 4001 but not longer on the audience, connected to it

ping upgrade.mikrotik.com from pc connected directly to the 4011 works fine
ping upgrade.mikrotik.com from pc connected directly to the audience works fine too

pining upgrade.mikrotik.com from cli in 4011 works
pining upgrade.mikrotik.com from cli in audience fails


can somebody please help to troubleshoot, I assume can be a bug introduced in 6.47.2 or further on the audience?

thanks

the issue has been resolved by resetting the device and recovering the config…what…
