This is happening randomly, continues 2-3 hours a day. Happened for 4-5 times. My app was running for a longer time and there was no problem until recently. I would appreciate any insights. Where should I looking for the cause of this problem?

Apparently some kind of DDOS attack was causing the issue. I don’t exactly know the details of why or how it does create this problem but for now we were able to mitigate it.
