Sap - Time out error
Collected information from the user and asked to clear his browser history. No succes. Tried to reinstall Sap version from the jnj app store, but app store was not opening. See screenshot. I opened another ticket for the app store issue because user said this Sap issue needs to be solved urgent.  
Resolution: Installed SAP GUI 800 in client machine and user confirmed the issue is resolved.
