Hello Everyone,

We are using ISE version 2.3.0.298 patch 6,7 in virtual environment. We are trying to do TC-NAC from ISE GUI with AMP cloud but it show error "ERROR: while trying to connect to AMP cloud " in vendor instance while trying to connect AMP.  When we checked the log in ISE using “show logging container tc-nac container-name <InstanceName> log-name adapter.log tail” command it show error "[Get clouds received RequestException ("bad handshake: Error([('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')],)",)].
