Our library recently created a z39.50 server (Koha 20.05). We are implementing OCLC Discovery. They can successfully connect to our server, but the connection closes during the attempt to retrieve the data (init 1020 error). How do we allow the connections to stay open in order for OCLC to retrieve our information? Thanks in advance!
