Important points:

1. Look at the size of your project in harbor (does storage allow limits)
2. As colleagues said, if you have 1 nginx or more and the route goes through them, write in the server block (blocks if u have many NGINX)

server {
    # disable any limits to avoid HTTP 413 for large image uploads
    client_max_body_size 0;
}

thank you very much to the guys at the top
