If you delete that 0kb file and try again do you end up in the same position, or does it now work? We've been unable to reproduce anything like this so far.

I can save hipfile , render image to server, cache usd or bgeo to server, but Can't save renderGallery.

Does a galleriessubdirectory of $HIPalready exist? If so, do you have permissions to write into it? If not, do you have permissions to create it?

I'd agree that forum post is not a bad place to begin, and let's see whether that provides enough context for more targeted questions. Either way, let me know and I'll pick it up from there.
