Hi All,

 

I had left my AEM instance up and running over the night but found the instance not working with the below error -

Could you please help in identifying the root cause of the issue ?

Update - 24/July/2022

I had set up another instance on another port to work for the day. But when I turned off the instance and brought it up again I got the same errors -

    @b_sravan - I am using Java version 11 and AEM Version 6.5 (aem-sdk-2022.4.7138.20220427T075748Z-220401)


    the filename indicates that you are NOT using AEM 6.5, but rather the SDK version of AEM as a Cloud Service. Java 11 is supported and should work.

     

    Restarting should fix the problem for the moment, I am aware that a fix in this direction should be included soon-ish into the SDK.

    Did you try restarting the server? Please try it might help.

    Also please check if all bundles are in Active state.

      Hi Sachin, Thanks for replying

      The /system/console/bundles won't open up either for some reason.

      Not sure what is the issue. For now I have migrated to another instance on a different port.

        Usually the session ends when the instance is inactive for a certain period of time.
        Please restart your instance, it should work.

         

        If you wish not to restart, please go to localhost:4502/system/console/bundles and if login page is prompted please login using your credentials and check if all the bundles are in active state.

        Thanks,

        Sravan

          Hi Sravan,

           

          Thanks for the response. I tried instance restart as well back then but didn't work.

          Have migrated to another instance for now but will try to bring up the server again and let you know.
