Hi Mikrotik,
Our router RB1100AHx4 Dude Edition, with Dude enabled RoS 6.46.6, it’s been twice in last 30days this router can’t be accessed from winbox / telnet / ssh.
The service running okay, NAT routing, but DHCP Server, Dude, VPNs all are down.
In the log showing warning about this, I don’t know what is this
timeout while waiting for program 20
timeout while waiting for program 24
Is this a bug ?
Hi,
im also having the same problem with the same router
ive had this problem however for the past 6 months and ive given up, we are unable to replace it as the replacements are too expensive and we require the fallover port as well 
from what ive read up in other posts and abit of googling
it seems all TCP/ICMP stuff goes tits up?
UDP however works fine? because i was able to connect to our cameras behind our router which use UDP no problem,
but anything TCP, no luck?
only way i found of fixing this was to physically restart the router as even the local console via serial lead was locked up
i think its a faulty device
Regards
Simon
