Greetings.

I got a eduroam setup with Mikrotik AP's with respective shared secrets and RB1200 as a DHCP server.
Two days ago, the customer started filling complaints that he was unable to connect to the network at
times. By setting up extensive logging I managed to see few error messages that occur frequently, most
are:
session-timeout=180

but, as mentioned before, two days ago I started seeing:

sending 05:00 to RAIUS_server_IP:1813
could not send packet: Cannot assign requested addresses.

I can not find any solution as of yet, and nothing in documentation.
Did anyone have a similar problem, and what could be the solution to this issue.
