The problems that you have been experiencing are most likely related to the server environment, on which the project is hosted. The WorkflowBaseURL property is indeed required, but it may not resolve the issues with the endpoint error, if the environment is more complicated or there are some redirections / applied to the website /server, which are misleading the workflow.
If possible, please provide screenshots of the following files, so we can understand what is happening on your end:
- server's hosts file
- IIS site bindings
Any additional information about the server setup and environment would be helpful.
