Reading (two number) electric only digital meter

My electric only meter is digital and internet connected. However for the first time in 4 years I could not get readings when pressing the ‘A’ button (or the other one just in case!) All it would give is some sort of total import in kwH. This persisted over at least a 10 minute period.
What may be wrong? Is it a likely intermittent connection or is my meter hacked?
