The LEDs, "Power", "ERROR" and "RUN" are not shining, but I/O LEDs are ON so I would say you have PLC malfunctioned. Also, hudging by the color of SC09 it is not original cable. However, I would try to download drivers from MyMitsubishi.

The most common reason for that fault is the baud rate is too high.
Set it to 9600 and you'll connect.

Ronnie, Should not matter as the FX Defaults to 9600 after power up, Both GXDev, Works & Beijers test at this then sends commands to adjust to the selected baud rate, found this out when I talked to Kepware regarding a problem after power up of PLC defaulted to 9600 but GX versions & Beijers would always connect even at 57k. But then again the interface cable does look like a clone & it may depend on the USB to 232 converter being good quality.
The only other time I have had this is wrong parity, stop bits etc. never on baud rate.

All I can say is I've had the same fault and it was making a connection but faulted on upload.
I changed baud and all was well.
Can't harm to try

First do a Clear All, if the PLC has corrupted data you need it.
