I found a lot of logs said, which will cause this issue: 2021-11-04T06:07:41.575Z [ERROR] core: error during forwarded RPC request: error="rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp: lookup vault-2.vault-internal on 172.20.0.10:53: no such host"" 2021-11-04T06:07:41.575Z [ERROR] core: forward request error: error="error during forwarding RPC request" 2021-11-04T06:07:49.661Z [ERROR] core: error during forwarded RPC request: error="rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp: lookup vault-2.vault-internal on 172.20.0.10:53: no such host"" 2021-11-04T06:07:49.661Z [ERROR] core: forward request error: error="error during forwarding RPC request" 2021-11-04T06:08:10.232Z [ERROR] core: error during forwarded RPC request: error="rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp: lookup vault-2.vault-internal on 172.20.0.10:53: no such host"" 2021-11-04T06:08:10.232Z [ERROR] core: forward request error: error="error during forwarding RPC request" 2021-11-04T06:08:39.022Z [ERROR] core: error during forwarded RPC request: error="rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp: lookup vault-2.vault-internal on 172.20.0.10:53: no such host"" 2021-11-04T06:08:39.022Z [ERROR] core: forward request error: error="error during forwarding RPC request" 2021-11-04T06:08:49.376Z [ERROR] core: error during forwarded RPC request: error="rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp: lookup vault-2.vault-internal on 172.20.0.10:53: no such host""

Hello! This looks like a DNS resolution error. It's attempting to resolve vault-2.vault-internal to an IP address and cannot. Are you able to perform an nslookup from the host and have it resolve?

Hi @anemptyair - just a quick note here, I'm going to go ahead and close this issue for now, but please do feel free to re-open it if you need. :) Thanks for understanding!
