Image from camera connect api not working in connect

Hello, I have little script that runs on my rpi. 

script is simple

#!/bin/bash

# Set default values for environment variables
: "${HTTP_URL:= https://connect.prusa3d.com/c/snapshot }"
: "${DELAY_SECONDS:=10}"
: "${LONG_DELAY_SECONDS:=60}"
# FINGERPRINT can be a random string with at least 16 characters
: "${FINGERPRINT:=fprint}"
# CAMERA_TOKEN generated by the Connect server
: "${CAMERA_TOKEN:=token}"

while true; do
    # Grab a frame from libcamera-still with the highest resolution
    # that is displayed on Prusa Connect: 1704 x 1278 for a 4:3 image
    # Setting the quality to 80 saves almost 50% in file size for
    # very little decrease in quality. Set to taste!
    # If you need to rotate the image 180° add --rotate 180
    # libcamera-still -v 0 --immediate --width 2274 --height 1280 -q 80 -o output.jpg
    v4l2-ctl --device /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=MJPG --stream-mmap --stream-to=/tmp/output.jpg --stream-count=1

    IMAGE_SIZE=`wc -c < /tmp/output.jpg`
    # If no error, upload it.
    if [ $? -eq 0 ]; then
        # POST the image to the HTTP URL using curl
        curl -X PUT "$HTTP_URL" \
            -H "accept: */*" \
            -H "content-type: image/jpg" \
	    -H "content-length: $IMAGE_SIZE" \
            -H "fingerprint: $FINGERPRINT" \
            -H "token: $CAMERA_TOKEN" \
            --data-binary "@/tmp/output.jpg" \
            --no-progress-meter \
            --compressed
	    #-v

        # Reset delay to the normal value
        DELAY=$DELAY_SECONDS
    else
        echo "libcamera-still returned an error, retrying after ${LONG_DELAY_SECONDS}s..."
        
        # Set delay to the longer value
        DELAY=$LONG_DELAY_SECONDS
    fi

    sleep "$DELAY"
done

scripts is running, i can download image to my pc and its working. But prusa connect show no image 🙁 And its even gets always 204 status code from api. What am I doing wrong?
