I am facing the classic HTTP error 503 while restarting my AEM instance.

Error logs state the following

Possible reason is missing repository service. Check AuthenticationSupport dependencies

 

I have checked that my bundle "Apache Sling Authentication Service (org.apache.sling.auth.core)" is active

I have followed the steps mentioned in this post

I have given the instance a good one hour to start completely

None of the above steps helped fix my issue.

 

Please suggest any methods you're aware of to troubleshoot this issue. I'm so stuck.

Hi @apoorva_arza,

Please check all the available existing error.log files(logs rotated with previous days) in your local instance before you get to notice the exact log statement - "AuthenticationSupport service missing".

Share the initial statement that logged as "Error" level. 

Recently ran into the issue in one of my local instance and the original/initial cause was  Java Heap Space (java.lang.OutOfMemoryError: Java heap space) which then eventually lead to "AuthenticationSupport service missing" - While setting up the new instance, I missed to configure the JVM options in start.bat and was using the default one.
