Subject: Unable to switch inputs via web-GUI but switching inputs (manually) via telnet session works
Solution:
To resolve this issue, log into the matrix's web-GUI and check that "Telnet login mode" is not enabled (turned on). With this setting on, you must log into the telnet session each time you want to send commands.
After disabling the setting, make sure to hit "Save" to save the system settings.
