Greetings.

I got a eduroam setup with Mikrotik AP's with respective shared secrets and RB1200 as a DHCP server.
Every AP has its own public IP address for authentification on RADIUS server, and a private IP address
for connecting users to the 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.
