CISCO ACCESS CONTROL SERVER

[ugwuugochukwuk]

Hello All,

I have a cisco access control server in my environment.

I could access the GUI using Microsoft Edge browser, but recently I get the error below whenever I try to log onto the ACS server.

The connection for this site is not secure ERR_SSL_VERSION_OR_CIPHER_MISMATCH Unsupported protocol The client and server don't support a common SSL protocol version or cipher suite

I have tried  different browsers and issue still persists.

I have also cleared browser cache and the SSL state too.

Kindly assist.
