Wireless clients empty TLS message via one WLC

Hi all,

We have ACS 5.1, WLC 7.0.98.0 and EAP-TLS. Wireless clients trying to access the network via one of our WLC 5508s are not getting authenticated. I can see the following on ACS:

"11514 Unexpectedly received empty TLS message; treating as a rejection by the client"

which usually means certificate errors / CA problems but clients coming on via other controllers are fine. Any suggestions?

I saw another post which suggested to check the time and discovered that the controller in question was an hour out as the time delta was not set the same as other controllers. However correcting this has not helped.

Many Thanks

Scott

Hi Scott,

Looks like certificate has expired.

Login to Cisco Secure ACS
Navigate to System Administration / Configuration / Local Server Certificates / Local Certificates
Check the certificate expiry
Logon to Certificate Authority server to generate a new certificate
