Hi everyone,
what most likely could be a reason for WLC's syslog message like this:
"Unable to send EAPOL-key msg - invalid WPA state (0) error"
I have a SSID with radius (NPS) auth which has been working for about 2-3 years and accidentally stopped working on Monday. All clients are affected. When users try to connect to the SSID the just rejected. All certificates are OK.
Could you please share any your ideas? I can provide any additional info if needed.
Many thanks in advance, Ilya
Update:
Before 1 day SSID stopped working this message in WLC's syslog appeared:
: %ACL-3-ENTRY_DONOT_EXIST: acl.c:376 Unable to find an ACL by name "���"
