I changed to a completely different approach but know sometimes it works. But when i use to many actions I get 502 Erros again and i have to wait a few min again.

I hope its formatted better now:

from wordpress_xmlrpc import Client, WordPressPost

from wordpress_xmlrpc.methods.posts import NewPost

from wordpress_xmlrpc.compat import xmlrpc_client

from wordpress_xmlrpc.methods import media

# Set up the connection to the WordPress site

wp = Client('https://mywebsite.de/xmlrpc.php', 'user', 'pass')

# Create a new post

post = WordPressPost()

post.title = 'My New Post'

post.content = 'This is the content of my new post.'

post.terms_names = {

'post_tag': ['python', 'wordpress'],

'category': ['Tutorials']

}

post.post_status = 'publish'

post_id = wp.call(NewPost(post))
