FTDI troubleshooting.. 3 red flashes when loading sketch

Projects General Guidance
1

I loaded a sketch to a arduino pro mini via the FTDI232 with out issues. I made a few modifications to the sketch and tried to upload the sketch but now, no matter what I do I cant get this thing to work properly. When I start the upload I get 3 red flashes on the FTDI board and then 10 out of 10 attempts before it times out and doesnt load the sketch

i thought maybe it was drivers so I uninstalled and reinstalled them with no luck.. any ideas of what i could check?

and then 10 out of 10 attempts before it times out and doesn't load the sketch

That means your IDE is not communicating with the Arduino.
Lots of reasons possible for that, here are just a few:-

Arduino is broken.
Computer USB is broken.
Wrong com port is selected in the Tools menu.
Wrong type of Arduino selected in the IDE.
Broken USB lead or socket.

I ordered a new ftdi board. I tried different cable, pro mini, and verified com port and always get the same response. We’ll have to try again then

So it turns out that I had to make multiple attempts to uninstall and reinstall the usb drivers to get it to work
