Background:

I have a kubernates cluster in my cloud server,And i deployed spring boot application as a pod .Everything is ok before 2 week , but my application unexpectedly could not be accessed on Ferb 22.

I used command "kubectl exec -it <pod> sh ",curl 127.0.0.1:<port> in pods but no response .I saw my application logs but cant found error about this issue.I try to restart my applications ,but the same issue occur after two days.

I have no idea with this issues.Can any one help me ?

When everything ok ,i can call 127.0.0.1:18890 and have response immediately ,once issues happend it will be requested timeout .Only this kubernates service have this question ,others seems normal
