Since I'm using a free license, I can't seem to open a case. The root_endpoint in the /opt/splunk/etc/system/local/web.conf file is set correctly, and Splunk is working fine. I'm sorry, I didn't write it down clearly enough. If you use Lookup editor v4.0.1, https://splunk_address/splunk/ko-KR/app/lookup_editor/lookup_list page, the links are looking incorrectly like this https://splunk_address/app/lookup_editor/lookup_edit?... They should look like this https://splunk_address/splunk/ko-KR/app/lookup_editor/lookup_edit?... In Lookup editor v3.6.0 and earlier, it looks fine using the root_endpoint value.
