Hi We had a working Koha configuration to access the database of the German national library (Deutsche Nationalbibliothek / DNB) via SRU and HTTP. But since 19 July requests using the HTTP-protocol will be redirected to the HTTPS-protocol by "HTTP-Statuscode 301 Moved Permanently" (see https://lists.dnb.de/pipermail/ons-sru-ru/2022-July/000015.html). The search via HTTPS is working via yaz-client: # yaz-client https://services.dnb.de/sru/dnb Z> sru GET 1.1 Z> find "Marx" Z> s 1 So in our Koha configuration we changed port 80 to port 443 - but when searching anything Koha immediately (apparently without really searching) returns "Nothing found". It's is the same with both databases "sru/dnb" (bibliographic data) and "sru/authorities" (authorities). Has anyone been successful recently when trying to access the DNB databases via SRU and HTTPS?
