The "Update Elasticsearch index" jobs in our Koha installation are not being picked up by the background worker. This behaviour started a while ago while still running version 23.11. Now after upgrading to Koha 25.11, the problem persists. Elasticsearch: Version: 7.17.29 | Nodes: | Status: running Switching between STOMP or polling for JobsNotificationMethod does not make any difference. Any suggestions to resolve / diagnose this issue?
