I have SharePoint 2019 on premise environment consisting of an APP + Web server. I am trying to publish a simple SharePoint 2013 workflow but getting following error:
System.ServiceModel.ServerTooBusyException: The HTTP service located at http://APPServer:32843/a81ee7e967be4165b9ada2b6bc67fc4a/AppMng.svc is unavailable. This could be because the service is too busy or because no endpoint was found listening at the specified address. Please ensure that the address is correct and try accessing the service again later. ---> System.Net.WebException: The remote server returned an error: (503) Server Unavailable.
at System.Net.HttpWebRequest.GetResponse()
Workflow Manager is installed on Web server and when I go to Workflow Manager proxy in CA then it shows Workflow is connected. It's service is running in services.msc. How do I go about diagnosing and fixing this issue because may be workflow manager is not properly installed? Here's the current setup:
On APP server SharePoint Search Host Controller service is running in services.msc
On Web server SharePoint Search Host Controller is in disabled state. Trying to start it using same account which is being used on App server throws error that Windows cannot start service.
Both App Management and Subscriptions Settings service applications are started. App management service is running on both App and Web server.
How to fix the issue? By the way why the URL in error above even points to App server. Shouldn't it point to Web server because this is where Workflow Manager is installed!?
