I'm running a single instance of solr server 9.0.3. The "solr status" command confirms that the server is running and listening on TCP port 8983:
$ sudo -u solr ./bin/solr status Found 1 Solr nodes: Solr process 56803 running on port 8983 { "solr_home":"/opt/solr-9.3.0/server/solr", "version":"9.3.0 de33f50ce79ec1d156faf204553012037e2bc1cb - houston - 2023-07-17 17:13:17", "startTime":"Sat Sep 23 13:58:43 EDT 2023", "uptime":"0 days, 0 hours, 0 minutes, 14 seconds", "memory":"138.7 MB (%27.1) of 512 MB"} However, I can't connect to the server using a web browser or command like tool like curl: $ curl http://mysite.net:8983/solr curl: (7) Failed to connect to mysite.net port 8983 after 13 ms: Connection refused I *can* connect to this server when I switch to an installed older (8.11.2) installed version of solr. Did I miss something during the installation and configuration steps for this 9.0.3 instance? Thanks, Scott
