Since I have migrated my APs to ROS5, sometimes I have strange issues about winbox: I cannot connect to RB until I reboot it, while I can manage my device with mac-telnet or ssh.
I observed this issue only in BS and never in CPE: on RB532, RB600, Groove, with ROS 5.2, 5.5 and 5.6.
Is it a known problem? Does 5.11 solve this?

Thanks.
