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.
Solved! Go to Solution.
