External scaler goes to CrashloopBackoff state frequently

[IsuruBoyagane15]

I have been using the add-on to scale my deployments in a AKS cluster.
I have multiple workloads to be scaled. Generally, the system works as expected.

But, I see the external-scaler pod goes to CrashloopBackoff state frequently.
When I checked the log in the external-scaler, I found this error log.

{"level":"error","ts":1694510987.376597,"caller":"scaler/main.go:69","msg":"creating a queue pinger","error":"requesting the queue counts from http://10.0.7.206:9090/queue: Get \"http://10.0.7.206:9090/queue\": dial tcp 10.0.7.206:9090: i/o timeout","errorVerbose":"Get \"http://10.0.7.206:9090/queue\": dial tcp 10.0.7.206:9090: i/o timeout\nrequesting the queue counts from http://10.0.7.206:9090/queue\ngithub.com/kedacore/http-add-on/pkg/queue.GetCounts\n\t/workspace/pkg/queue/queue_rpc.go:76\nmain.fetchCounts.func1\n\t/workspace/scaler/queue_pinger.go:222\ngolang.org/x/sync/errgroup.(*Group).Go.func1\n\t/go/pkg/mod/golang.org/x/[email protected]/errgroup/errgroup.go:75\nruntime.goexit\n\t/usr/local/go/src/runtime/asm_amd64.s:1594","stacktrace":"main.main\n\t/workspace/scaler/main.go:69\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:250"}

As I understood, the external-scaler could not connect to the admin-service of one interceptor pod. (interceptor had 3 replicas in the deployment; 10.0.7.206 is the pod IP of one of the replicas)

I tried roll-out restarting external-scaler and interceptor pods. No luck.
During this time, the deployments that are supposed to be scaled to zero after the cool-down period (5 mins), were not scaled to zero in 5 mins.

Finally, I scaled interceptor deployment from 3 to 1. With that change, after some time, the setup started to work as expected.

Any possible reason for this behavior?
