hello

nodered, influxdb1.8.x and grafana are on 3 different VM.  
After i had to reboot the Node itself the vm rebootet without error but

nodered can't write down to influxdb  
grafana can't read data from influxdb

grafana say InfluxDB Error: Bad Gateway  
nodered say "Error: connect ECONNREFUSED 10.147.42.155:8086"

\*.155 is the influxdb server

doing a nmap again the influx server the Port 8086 is not there.

but on influxdb

# ss -tulpn

Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port  
tcp LISTEN 0 128 127.0.0.1:8086 0.0.0.0:\* users:(("influxd",pid=340,fd=125))

so i am confuse - and can't find how to solve it

thanks for any information

have a nice day  
vinc

Did you - by any chance - upgrade to Influx 1.8.9? They have changed the way it starts, which broke several setups on slower systems or with many shards.

If that's the cause, there are some workarounds.

It has also be discussed on the forum: [Influxdb upgrade from v1.8.6 broken [FIX] v1.8.9 still broken](https://discourse.nodered.org/t/influxdb-upgrade-from-v1-8-6-broken-fix-v1-8-9-still-broken/50459)

but local i can start it, it is just from the other VM, nodeRed server VM, the ip and port are not there, ping is ok too

Is influx definitely running ok? In the influx VM can you access the server via that port?

You said ping is ok. Do you mean that from the node red server you are able to ping the ip of the influx VM? Do the VMs have separate IPs or have you bridged the networking?

nmap does not default to all ports. Try  
`nmap 10.147.42.155 -p-`

Are you _absolutely_ sure that the IP of the VM is what you think. I have on more than one occasion spent ages trying to analyse problems like this only to realise that I was talking to the wrong machine.

as node red give this error - would say yes

```auto

msg : error
"Error: connect ECONNREFUSED 10.147.42.155:8086"

```

and on the other side

```auto
dbflux18:~# ss -tulpen

```

could it be i should change to the real address

````auto
# vi /etc/influxdb/influxdb.conf

line 260 bind-address = "127.0.0.1:8086"```
````

Why does that make you thing that the ip address of the influx vm is 10.147.42.155? In fact it makes me think it may be the wrong address. There is obviously a machine at that address but which one is it? That is the question.

In the influx machine what does `ifconfig` show, or if that is not installed `ip addr`.

Did you edit that? Normally you should leave it commented out (unless the default has now changed). Then it should default to any address, port 8086. Then in `ss` it shows as `*:8086`

i think it is corrct because befor the node reboot and the VM update it did work like this  
it looks like the port is not open from a other vm

Thinking is not enough. Check it with ifconfig or ip addr.

@Colin this is done access with port 22 works fine

```auto
dbflux18:~# ip a
inet 10.147.42.155/24

```

also is the vm with influxdb sending update to munin.

the problem is i think just this port 8086

You didn't answer my question about whether you edited the bind\_address line? If you didn't then what do the comments before it say?

If it is bound to 127.0.0.1:8086 then it should not respond on the 10 address

sorry @Colin i am not sure if i did!

@dceejay if it is not respondig - it will not connect - so i would have to change it

Looking at the docs you should set that to  
`bind-address = ":8086"`
