Workflow fails to run Http 404 error RRS feed

  • Question

  • All our 2013 workflows failed to run after servers been patched with March CU 2018 and also Workflow Manager CU5. Strangely, this error still persists after they rolled back the whole farm (vms and databases) to an unpatched stage. Has anyone got any clue what this could be related to?

    Whenever you start *any* Sharepoint 2013 workflow, it will just sit there with a Http 404 error and a retry sign. And then after awhile, it ended up in suspended status. 

    No errors in the event log, except many service bus related warnings. No application error either.

    The workflow manager is using the farm account. Sharepoint 2010 workflows work though.
