URL: https://github.com/apache/apisix/issues/9415
### Current Behavior
When configuring similar clb nodes and IP nodes in upstream nodes at the
same time, there will be node exception errors for clb nodes.
### Expected Behavior
All nodes should be normal.
### Error Logs
```
[error] 54#54: *338255 [lua] balancer.lua:82: fetch_health_nodes(): failed
to get health check target status, addr: 39.156.66.14:80, host: nil, err:
target not found, client: 172.18.0.1, server: _, request: "GET /hello
HTTP/1.1", host: "127.0.0.1:9080"
```
### Steps to Reproduce
1. upstream config just like
```
{
"id":"459301800810382014",
"create_time":1683294806,
"update_time":1683295767,
"nodes":{
"172.18.0.4:80":1,
"172.18.0.5:80":1,
"www.baidu.com:80":1
},
"timeout":{
"connect":6,
"send":6,
"read":6
},
"type":"roundrobin",
"checks":{
"active":{
"concurrency":10,
"healthy":{
"http_statuses":[
200,
302,
404
],
"interval":1,
"successes":2
},
"http_path":"/",
"timeout":1,
"type":"http",
"unhealthy":{
"http_failures":5,
"http_statuses":[
500,
501,
502,
503,
504,
505
],
"interval":1,
"tcp_failures":2,
"timeouts":3
}
}
},
"scheme":"http",
"pass_host":"pass",
"name":"test",
"keepalive_pool":{
"idle_timeout":60,
"requests":1000,
"size":320
}
}
```
or the configuration in the background looks like this
2. route config just like
```
{
"id":"459301861040587454",
"create_time":1683294842,
"update_time":1683296659,
"uri":"/*",
"name":"test",
"methods":[
"GET",
"POST",
"PUT",
"DELETE",
"PATCH",
"HEAD",
"OPTIONS",
"CONNECT",
"TRACE",
"PURGE"
],
"upstream_id":"459301800810382014",
"status":1
}
```
3. Initiate a request
```
curl http://127.0.0.1:9080/hello -i
```
4. the following error occurs after a health check is triggered by request
```
[error] 54#54: *338255 [lua] balancer.lua:82: fetch_health_nodes(): failed
to get health check target status, addr: 39.156.66.14:80, host: nil, err:
target not found, client: 172.18.0.1, server: _, request: "GET /hello
HTTP/1.1", host: "127.0.0.1:9080"
```
