flask image upload not working on server , showing permission issue

Question

I am trying to upload an image using flask uploads, but it is not uploading (python 3.6), I have also given www-data user and group to static folder and given 777 permission also , but it's still not working:

photos = UploadSet('photos', IMAGES)
app.config['UPLOADED_PHOTOS_DEST'] = '/static/'
configure_uploads(app, photos)

ERROR : File "/var/www/html/eiapp/eiapp/__init__.py", line 94, in upload photos.save(file) File "/usr/local/lib/python3.6/dist-packages/flask_uploads.py", line 422, in save, referer: http://142.93.212.243/eiapp/uploadform os.makedirs(target_folder), referer: http://142.93.212.243/eiapp/uploadform File "/usr/lib/python3.6/os.py", line 220, in makedirs, referer: http://142.93.212.243/eiapp/uploadform mkdir(name, mode), referer: http://142.93.212.243/eiapp/uploadform PermissionError: [Errno 13] Permission denied: '/static/', referer: http://142.93.212.243/eiapp/uploadform

@app.route('/uploadform')
def upload_file_form():
    return render_template('upload.html')

@app.route('/upload',methods=['POST','GET'])
def upload():
if request.method=='POST' and 'file' in request.files:
    file=request.files['file']
    filename = secure_filename(file.filename)
    photos.save(file)
    return 'uploaded'
