Unable to login into CCR1036-8G-2S+ via winbox mac

Hi all,

i just bought 2 unit of CCR1036-8G-2S+ and upgraded to ros 6.5 and bootloader 3.10.
Winbox loader is 2.2.18 and i cannot access via mac address to CCRs.
However i can login into ccr without problem via mac-telnet from RB751,
so i also tryed to reset configuration skipping default-configuration but the problem persists.
Winbox scan shows correctly mac address of CCR but it timeout when i try to access.
The unit is directly connected to PC, i manage without problem any other ros device.

the hard work.

I’m having the same problem.

THe problem did not involved on another PC. but this behaviour is very strange.
I never had same issue first, i always used winbox with other 100+ ros devices since years..
