dSpace 9 cannot connect to solr (even after checking the recommended troubles)

[Matyas F. Bajger]

Hello!

Please, would you be so kind and could help me with installation of new
dSpace 9. The Dspace (Spring Boot) cannot connect to solr. I have pasted
the dspace.log below.

I have checked this pretty described troubleshooting at
https://wiki.lyrasis.org/display/DSDOC9x/Installing+DSpace#InstallingDSpace-Solrrespondswith%22Expectedmimetypeapplication/octet-streambutgottext/html%22(404NotFound)
(thanks for this) and corrected the problems.

Solr is listening - checked by
curl  "http://localhost:8983/solr/admin/info/system"
when I get the correct json response  or "http://localhost:8983/solr/" -
getting the solr webpage

Solr is defined in local.cfg:
solr.server = http://localhost:8983/solr

dSpace configs has been copied tot /opt/solr/server/solr/configsets/
All solr dirs and subdirs /opt/sorl and /var/solr are owned by solr user
(used for running solr)

Solr log /var/solr/logs/solr.log claims an error when executing :
2025-09-26 05:58:55.865 ERROR (qtp801569151-34) [c: s: r: x:
t:localhost-1] o.a.s.s.SolrRequestParsers Couldn't get multipart parts
in order to delete them => java.lang.IllegalStateException: No multipart
config for servlet

        at org.eclipse.jetty.server.Request.getParts(Request.java:2328)
~[jetty-server-10.0.22.jar:10.0.22]

But I am not sure if this might be a problem and how to solve it.

Please, any help or pushing me to solution appreciated!
Thanks in advance and have a fun not only with dSpace!
