Hi we are having a problem in our production environment, all of our Applications with Workflow 2013 are no longer working since yesterday.

I already did below steps but still no luck:

  1. Restart and Recycle WorkflowMngmt App Pool
  2. Restart WorkflowManager Backend

enter image description here

This is what I get in ULS Log

I can still published the workflow and access 12290 WorkflowUri though.

Any help is appreciated! Thanks!

    Lastly also check the service bus services from workflow manager servers as these services are responsible for the communications. Please make sure service bus gateway and service bus message broker service started on all wf manager servers. If these are already started try to restart them. Commented Aug 18, 2016 at 4:53

You are getting a time-out error that means SharePoint is unable to communicate with the workflow manager sever.

Service bus at workflow manager is responsible for the communication between SharePoint and WFM. Please make sure these 2 services are started on all WFM servers.

  1. Service bus gateway
  2. Service bus message broker
