Error when selecting Incidents from the side menu on the unified portal (endpoints and email)

Hi,

The incidents option has worked before and was quite happy listing my incidents. Now i get the following:

Error Loading items

Failed to GET from /incidentQueue/incidents/alerts/. Status code: undefined

I can still go to individual incidents either from an associated alert (which are listing ok) or from the incident link from Sentinel.

Any help would be much appreciated...

Thanks,

Tim
