Infor OS 503 Service Error (111)

If you receive a 503 Service Error (111) after an Infor OS install or update, it is possible that the SAML configuration was not properly deployed.  Another symptom of this issue is if the Grid-XiPlatform application doesn’t show up under Applications in the InforOSManager.

To resolve this issue, try to redeploy the Core SAML.  Log into the InforOSManager and click on the main Infor OS instance.  Click the button “Redeploy Core SAML”.  Once it is successfully deployed, click the Save button.  Then, reboot the server.

To validate, make sure that the Grid-XiPlatiform application is available in InforOSManager.  Now, the grid home page should load.
