Hello Bruno,

The actual reason was quite a bit simpler: The receiving server
required a certain keyword to be first in the request - which I was
not aware of. So now it works - but it's not perfect:

Is there a way to stream the file content over the connection? The way
it works now, the whole file is loaded into memory, right?
