In v6, Solr runs with the LocalHostRestrictionFilter, which rejects
queries from any address other than 'localhost' (127.0.0.1, ::1). I
would check the DSpace configuration to see that 'solr.server' (in
config/local.cfg) is set to use a localhost address.
It is possible to disable the LocalHostRestrictionFilter if you need
to use a non-loopback address, but understand that Solr is not
designed to be exposed to the entire Internet. If you remove the
restriction, you should make certain that Solr is firewalled against
outside access.
