Could you please white list the following sparql endpoint:
https://nfdi4culture.de/sparql
This is a sparql endpoint used at nfdi4culture.de, an Oxigraph-based KG for research data maintained by the NFDI4Culture (National Research Data Infrastructure for Cultural Heritage) project based in Germany.

@Loz.ross Sorry for the delay, we've added the endpoint. Can you confirm it's working with an example query?
Hi @RKemper,
Thanks so much for working on this ticket! We tried a query with my colleagues, but we're getting an error:
Unknown error: Service URI https://nfdi4culture.de/sparql is not allowed
Perhaps you can check on your end if something is still blocking us? This is the query: https://w.wiki/96ES
@Loz.ross Yes the change to allowed endpoints did not get properly deployed; we've fixed that now. However there's another issue now that we've gotten past the Service URI not being allowed:
Unknown error: Could not identify format for service response: serviceURI=https://nfdi4culture.de/sparql, contentType=application/n-triples : response=
Based off T339347#9152553 I'm pretty sure that your endpoint needs to be able to produce application/sparql-results+xml in order to communicate properly with WDQS
@RKemper : could you add a curl example of the kind of queries we send and the response we expect?
Here's an example curl command we can use to verify when the service is properly supporting application/sparql-results+xml:
curl -k -XPOST -H"Accept:application/sparql-results+xml" --data-urlencode "query=select * { <iri1> <iri2> <iri3> } LIMIT 1" https://nfdi4culture.de/sparql
I'm marking this task as resolved until we hear back from OP; at that point the task can be reopened.
