Error details here:
The execution of template action 'Respond_to_a_PowerApp_or_flow_for_Success' is failed: the client application timed out waiting for a response from service. This means that workflow took longer to respond than the alloted timeout value. The connection maintained between the client application and service will be closed and client application will get an HTTP status code 504 Gateway Timeout.
Please assist any other workaround for this error
I got the same error today, Yesterday it run properly. Is it MS's problem?
