Getting an "Unable to retrieve company mappings" 500 error when using the Report API 1.4

[#1]

Hi, I was running some reports yesterday and out of nowhere I got this error:

{

    "error": "server_error",

    "error_description": "Unable to retrieve company mappings"

}

Using:

https://api.omniture.com/admin/1.4/rest/?method=Report.GetQueue

I have since not been able to run any API calls. 

Could someone please shed some light on this? 

Best
