failed to lookup SRV records

[Dauber01]

when i add the head of "dnssrv+_grpc._tcp." i got a error like the picture show caller=resolver.go:99 msg="failed to lookup SRV records" host=_grpc._tcp.thanos-receive-ingestor-default.namespace.svc err="no such host" and when i don't add the head , it work as well，so what should i do if i want to use the head "dnssrv+_grpc._tcp." at the verson of 24 in kubenets v1.20.10

The error is fixed because labeling was not done properly

i have same problem when i try to connect to memcached i have service memcached-thanos-system In thanos-store:

- |-
          --index-cache.config="config":
            "addresses":
            - "dnssrv+_client._tcp.memcached-thanos-system.{{ .Release.Namespace }}.svc.cluster.local"
          "type": "memcached"
        - |-
          --store.caching-bucket.config="blocks_iter_ttl": "5m"
          "chunk_object_attrs_ttl": "24h"
          "chunk_subrange_size": 16000
          "chunk_subrange_ttl": "24h"
          "config":
            "addresses":
            - "dnssrv+_client._tcp.memcached-thanos-system.{{ .Release.Namespace }}.svc.cluster.local"
          "type": "memcached"

I got msg="failed to lookup SRV records" host=_grpc._tcp.memcached-thanos-system.prometheus-system-layer err="no such host"

But from other pod, i run nslookup memcached-thanos-system.prometheus-system-layer and this work, dns resolve ip

Help please, Any ideas? @Dauber01 Did you solve the problem?

UPD:

I use

"addresses":
            - "memcached-thanos-system.{{ .Release.Namespace }}.svc.cluster.local:11211"

Instead

"addresses":
            - "dnssrv+_client._tcp.memcached-thanos-system.{{ .Release.Namespace }}.svc.cluster.local"

And this work for me

@subbuedcast could you elaborate on this? which labels on which pod/s were incorrect and how did you fix them?
