Resolution | When you create ECAT agent using packager under the security tab, you choose client certificate, server certificate and ports needed from communication between ECAT agent & ECAT console server as per screenshot below

Now make sure they are the same values included in the following configuration files ConsoleServer.exe.config under ECAT server directory
<add key="LocalHttpsServerPort" value="443"></add> <add key="LocalUdpServerPort" value="444"></add> <add key="LocalHttpsServerCert" value="EcatServerExported"></add> <add key="LocalHttpsClientCert" value="EcatClientExported"></add>
If values are not matched for some reason, there will be a communication failure or agent won't show as online in ECAT UI. |
