ESP8266 doesn't accept AT Commands anymore

So recently I've been working on some kind of project that uses arduino and esp8266 to make an HTTP get request from a basic website that I created. But somehow I messed things up while sending AT commands using the arduino Serial monitor. Now I doesn't accept any AT command and as soon as I open the Serial monitor I always get this message :

220---------- Welcome to Pure-FTPd [privsep] ----------
220-You are user number 19 of 500 allowed.
220-Local time is now 13:29. Server port: 21.
220-This is a private system - No anonymous login
220 You will be disconnected after 3 minutes of inactivity.
I'm just want to be able to communicate with it using its AT commands again .

Any help would be much appreciated :slight_smile:

Have you tried re-flashing the AT firmware? I had one of mine quit talking and after re-flashing it worked fine. Google will lead you to the software and bin files to flash it.
