Can you upload the blend file where it doesnt work? also looking at the screenshot you have liquid option turned off, and you cant really have a fluid sim without any liquid.

Unfortunately it doesn't work again. I tried everything. Sometimes it works and sometimes it doesn't.

I think I get it. So after a lot of trying I came to the conclusion that the last object must be sphere type flow. Only then does it work. If we first create a sphere and then a cube type domain then it will not work. I think that's the solution.

I think the issue in the first file was just that the face normals of the flow object were pointing to the inside. They should be pointing outwards like in the second file.

The order in which the object are added to the world should not make a difference.
