This was originally posted under OPNsense 25.7...but looks like I should have posted it here instead :-)
After upgrading to OPNsense 25.7, the Elasticsearch service does NOT restart after a firewall reboot. I can fix it and get it to start by going to services>Elasticsearch>General and click on the SAVE button. The enabled box is already checked, and the service fails to start until I clink on SAVE. Once I click SAVE, the service starts up and Zenarmor works great.
I am using the remote Elasticsearch DB with the os-elasticsearch7-maxit plugin from the mimugmail repo. I have uninstalled / reinstalled the DB and have the same result, the Elasticsearc service does not start and trying to manually start the service fails until I click the SAVE button.
I'v read that clicking the SAVE button rewrites the config file, allowing the service to start...but my guess is the file is NOT being saved?
