ERROR_GETTING_RESPONSE_FROM_BACKEND.messages

[MdV]

Hi team.Can you 

Since last night we are getting ERROR_GETTING_RESPONSE_FROM_BACKEND messages when downloading PLACEMENT_PERFORMANCE_REPORTs with yesterday's data for about 50 accounts. Restarting doesn't seem to help.

API version: V201609

Fields being queried:

DATE
, ID, CAMPAIGN_ID, AD_GROUP_ID, DISPLAY_NAME
, IMPRESSIONS, CLICKS, COST
, GMAIL_SAVES, GMAIL_FORWARDS, GMAIL_SECONDARY_CLICKS

Can you tell me what is going on?

Thanks,

Marcel
