HTTP ERROR 503 Problem accessing /. Reason: AuthenticationSupport service missing. Cannot authenticate request.

Hi @akshaybhujbale ,

To fix this, either remove the Repoinit file from the configs if not using or replace it with a org.apache.sling.jcr.repoinit.RepositoryInitializer-.config file from both the project you are deploying and the /crx-quickstart/launchpad/config/org/apache/sling/jcr location in file system.

Hope that helps!

@akshaybhujbale Please check that all OSGi bundles have the status “ACTIVE” in the OSGi console.  Start any bundles that do not have the “ACTIVE” status and this should resolve the issue."

If the issue persists, you may have to reinstall AEM from a fresh copy, install the update 1 package, restart (wait until error.log shows no more activity) and finally reinstall your installed packages manually.

Also, this could be the case, where you might have corrupted the indexes [Solution:- Stop AEM instance and delete Index files in crx-quickstart folder. restart Instance].

Last, check if bundles's dependencies are not present or packages dependencies are met or not.

Hope this helps!

Thanks
