Max retries exceeded with PiHole url

[lenkeybalis]

Dear Maintainer,

I use the docker-compose base setup. The pihole-exporter is running with PiHole server on the same server.

version: "3.9"
services:
  pihole-influxdb:
    image: avojak/pihole-influxdb:latest
    container_name: pihole-influxdb
    restart: unless-stopped
    environment:
      - "PIHOLE_ALIAS=pihole"
      - "PIHOLE_ADDRESS=http://192.168.0.30:80"
      - "PIHOLE_TOKEN=***********************************"
      - "PIHOLE_NUM_TOP_ITEMS=25"
      - "PIHOLE_NUM_TOP_CLIENTS=25"
      - "INFLUXDB_ADDRESS=https://*********************"
      - "INFLUXDB_ORG=influxdata"
      - "INFLUXDB_TOKEN=***************************************"
      - "INFLUXDB_BUCKET=pihole"

There are the following errors In the log :

pihole-influxdb  | 20:00:23 [ERROR] [pihole] Error connecting to http://192.168.0.30:80: HTTPConnectionPool(host='192.168.0.30', port=80): Max retries exceeded with url: /admin/api.php?summaryRaw&topItems=25&topClients=25&getForwardDestinations&getQueryTypes&auth=dd3ce459b1285a539966dc39                                                                  6bbbaa2d6ac2a002f7b3f36256d9fb3ce0e983e8 (Caused by ConnectTimeoutError(<urllib3.connection.HTTPConnection object at 0x7d969d798920>, 'Connectio                                                                  n to 192.168.0.30 timed out.

I checked the connection from the same machine via cUrl.

The connection is working fine. Did you observe this kind of problem in the past or it would be a specific problem only for me?

Thank you so much for your help!

I checked with native python scrip based execution. It seems to be working fine without issue. So maybe there will be the problem with my docker configuration or setup.

Now I found the issue I needed to use this option in the docker-compose.yaml file.:

network_mode: "host"
