By default, Unimus uses 10 second timeouts for SSH / Telnet connections. This means that if your device takes longer than 10 second to establish an SSH / Telnet session, Unimus will not connect to it (fail the connection attempt). This timeout is controlled by the unimus.core.connect-timeout setting.
During device Discovery (more info here), Unimus will establish multiple consecutive sessions to a device to test credentials (unless credential binding is used). Unimus waits 500 ms between session establishments by default. Especially for older / slower devices, or for purposes of slowing down device logins due to load on a central AAA system, it can be beneficial to increase this inter-connection delay. This timeout is controlled by the unimus.core.inter-connection-delay setting.
