Error in profile creation in Analytics GUI - RetrieveResult()

I am getting the following flow of events:

14/05/2018, 15:15:07
Start/Request profile of Dataset

2018-05-14 15:15:21.298
GetProfilesAMS: Error calling RetrieveResult(): JavaException: com.thingworx.common.exceptions.GenericHTTPException: [ProfilingMicroserver] could not retrieve result for jobId [15ac9974-3fa7-449e-b05d-9aa8f6b7778c]: Unable to retrieve results at results:/profiles/15ac9974-3fa7-449e-b05d-9aa8f6b7778c. Received response: {"code":404,"message":"Could not retrieve result [15ac9974-3fa7-449e-b05d-9aa8f6b7778c]"}

This last message is constantly surging. Basically it seems analytics is stuck in trying to get results. Until today (1 day later) I have a running profile job request.

When I try to delete:

2018-05-14 15:51:00.745
DeleteProfileAMS: ERROR deleting signal job: jobId=15ac9974-3fa7-449e-b05d-9aa8f6b7778c: JavaException: com.thingworx.common.exceptions.GenericHTTPException: Cannot delete a job in queued or pending state

Which is expected, but now every other profile request gets pending. Also, I'd probably encounter the same error if I tried. I already have had this exact problem and re-installed foundation and analytics.

Is there something we might have done wrong, possibly in installing ?

Thank you for you time,
