Webservice call hangs after 2 successive calls

I  created a microflow which calls a webservice. This microflow is invoked on an action button. In certain scenarios webservice is failing in such cases user is clicking the action button multiple times. First two clicks I get error from service which I show it to user and on third click response never comes back from webservice invoke action activity. After some time it throws timeout exception. I am not sure above issue is on Mendix side or thirdparty web services that I invoke. All services behave the same way. Any suggestions on fixing this issue is appreciated. Note: App hangs after above exception. I have to restart the App

From your question I gather that the user click on the button invoking the microflow to trigger the webservice call and an error is returned to the user, which you display. The error is being displayed by using the error handler function or is the error a return from the service?

This will happen a second time in the same fashion and only after the third time there is a timeout and the application hangs? My first step would be to investigate the logs and increasing the loglevel of the webservice log node, this might provide some more insight. When the time is only experience after a third time, I suspect the third party to handle this call differently, would investigate that. This should however not hang up the app, Hopefully the logging will provide some more clues.
