No response from consul http api


Some times, we are not getting any response from on consul client node and getting timed out . Surprisingly, we are getting the response immediately in the next iteration from same api.
Note: We don’t see any Resource issues(Cpu, memory or IO issues) and also there were no errors in consul.log as well.
Consul Version: 1.8.3

when does consul http api in hung state ? is any consul internal behavior cause this issue? if yes, why I don’t see any errors in consul.log

Kindly let me know if you any need further information.
