I have problems with grafana/influx.  
Influx is installed on a RaspberryPi4 with 4GB RAM in an ioBroker environment. After working flawlessly for some months recently it stopped working.  
ioBroker log indicates error:  
`Error: connect ECONNREFUSED 127.0.0.1:8086`  
After a new install of influx and a restore of the database it worked again for some days but stopped now.  
When calling “Influx” in monitor I get this response:

```auto
pi@raspberrypi:~ $ influx
Failed to connect to http://localhost:8086: Get http://localhost:8086/ping: dial tcp [::1]:8086: connect: connection refused
Please check your connection settings and ensure 'influxd' is running.
pi@raspberrypi:~ $

```

## Influxd is running and listening

```auto
pi@raspberrypi:~ $ sudo netstat -tulpn | grep LISTEN |grep influx
tcp 0 0 127.0.0.1:8088 0.0.0.0:* LISTEN 13217/influxd
pi@raspberrypi:~ $

```

indeed it seems to listen on 8088.

## as you can see in the influxdb.conf the Port 8088 is not selected

```auto
# The values in this file override the default values used by the system if
# a config option is not specified. The commented out lines are the configurati>
# field and the default value used. Uncommenting a line and changing the value
# will change the value used at runtime when the process is restarted.

# Once every 24 hours InfluxDB will report usage data to usage.influxdata.com
# The data includes a random ID, os, arch, version, the number of series and ot>
# usage data. No data from user databases is ever transmitted.
# Change this option to true to disable reporting.
# reporting-disabled = false

# Bind address to use for the RPC service for backup and restore.
# bind-address = "127.0.0.1:8088"

```

## – wheras in http section the correct Port 8086 is configured.

```auto
[http]
  # Determines whether HTTP endpoint is enabled.
enabled = true

  # Determines whether the Flux query endpoint is enabled.
  # flux-enabled = false

  # Determines whether the Flux query logging is enabled.
  # flux-log-enabled = false

  # The bind address used by the HTTP service.
bind-address = ":8086"

```

I check the installation

```auto
pi@raspberrypi:~ $ sudo apt update

```auto
pi@raspberrypi:~ $ apt policy influxdb*

pi@raspberrypi:~ $

```

Finally I tried again to call influx again and got this response:

```auto
pi@raspberrypi:/etc/influxdb $ influx
Connected to http://localhost:8086 version 1.8.10
InfluxDB shell version: 1.8.10
> show databases
ERR: Post http://localhost:8086/query?chunked=true&db=&epoch=ns&q=show+databases: dial tcp [::1]:8086: connect: connection refused
>

```

Suddenly it seems able to connect but cannot find any databases but still waiting for some input.

Has anybody an idea what I got wrong with this installation and how I can repair that?
