One of my apps recently started to reject random requests with timeouts. After some investigation I found out the following.
ssh into another app (gateway) in the same network and do
dig AAAA [my-problematic-app].internal, I get 2 IPs in the answer section. Looks like one of these IPs is correct (at least I can see it in the start up logs of the problematic app), and the other one is not. I tried redeploying the app and also tried scaling the count up and down (even to 0), but the bad IP doesn’t go away.
What can I do in this situation?
