Getting 503 error in AEM 6.5 publishers , authentication support missing
Hello Everyone,
I am using AEM 6.5 , in one of the publishers I am getting 503 error, I try to restart the aem service but no luck.
To fix the issue I try to delete below path but not working
crx-quickstart/repository/segmentstore/repo.lock
crx-quickstart/launchpad/felix/cache.lock
crx-quickstart/repository/index
crx-quickstart/launchpad/config/org/apache/sling/jcr/repoinit
Can anyone please help me to get back my server?
