Hi, The original error you shared seems to be saying that DSpace cannot connect to Solr:
ERROR unknown unknown org.dspace.discovery.SolrSearchCore @ Error while initializing solr server http://PUBLIC_IP:8983/solr/search <http://public_ip:8983/solr/search> You should double check that Solr is running at that IP and port. If not, you may need to modify the Solr configs. You also mentioned running Solr 9, while DSpace 8 currently supports Solr 8: https://wiki.lyrasis.org/display/DSDOC8x/Installing+DSpace#InstallingDSpace-ApacheSolr8.x(full-textindex/searchservice) The 502 Bad Gateway error sounds like it might be a misconfigured proxy. If you are running Nginx or Apache in front of the Runnable JAR, you may want to double check your settings in Nginx and/or Apache, keeping in mind the examples in step 16 (Production Installation) of the Backend Install: https://wiki.lyrasis.org/display/DSDOC8x/Installing+DSpace#InstallingDSpace-BackendInstallation You could also try to see if the backend works on port 8080, the default Tomcat port, first...and then try to setup the proxy as a second step. This is the process detailed in the installation guide.
