I tried:
curl -g -H 'Accept: application/rdf+xml'
'http://localhost:3030/ds/query?query=CONSTRUCTWHERE{}'
returned
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; >
</rdf:RDF>
so Fuseki does conneg.
What client are you using?
Are you sending the request direct or via a reverse proxy.
On your site there seems to be a reverse proxy (nginx) not letting
curl/wget through.
But using s-query and changing it to force "application/rdf+xml"
($accept_rdf="application/rdf+xml") does not work where is does work
with a local 3.14.0 server.
It looks like the reverse proxy.
If you run fuseki with "-v" it print the headers it receives and sends.
Adding "?format=xml" is another way to get application/rdf+xml. Some
client libraries aren't very good with HTTP hearers, and it's a
non-standard way to ask the server.

I am using with Postman to try and get rdf+xml. It was actually generated in a
script, so it has many more prefixes than it needs. Thank you very much for your
help. the request I send with Accept:application/rdf+xml return as response
Content-Type:text/turtle;charset=utf-8

Dear all,
I am probably missing something basic, but I am not sure how I can manage to
get RDF-XML as a format for my response from Apache Jena Fuseki.
I have tried sending in the request the Header Accept and Content-Type with
value application/rdf+xml,
"Accept:"
"Content-Type" refers to the request bod, not the response.
What request are you making? URL?
but in the first case I am returned turtle nevertheless, in the second I am
told in the response that The origin server is refusing to service the request
because the payload is in a format not supported by this method on the target
resource.
I am really not sure what this means and what I am getting wrong.
Thanks a lot for any hint!
