I have installed A2A client successfully but noticed it doesn't connect to PAM server. There is no firewall between A2A machine and PAM server. I can confirm cspmclientd process is listening on TCP/28888 port on A2A machine and from PAM Client's Credentials > Manage A2A > Clients page I can see the A2A machine is listed but the Version is shown as 0.0.0 and Connection Status icon is orange color.
The following error is seen in $CSPM_CLIENT_HOME/cspmclient/log/cspm_client_log.txt file.
