I have been running several dockers successfully , Sabnzbd, Radarr and Sonarr. I rencently ran into a problem with a share and had to delete the share and reinstall the three dockers. They had been working on 7.2 but now I cant seem to get Radarr and Sonarr to communicate with Sabnzbd. I have all three in bridge mode and the docker network setting is ipvlan. I 've tried host for the dockers but same result, Sonarr and Radarr can't seem to communicate with Sabnzbd using Sabnzbd's api. Diagnosticts are attached. Since I had this configuration working previously I suspect it's a networking problem. Any suggestions?

For this stack and more for IF I bring somehting down or need another docker... I wat depend on checks and health cheks... I prefer compose for Arrs setups...

???
did you clear out the old configurations for the *arrs by deleting the appdata configurations?

Example for unraid:
https://trash-guides.info/

https://trash-guides.info/File-and-Folder-Structure/
https://trash-guides.info/File-and-Folder-Structure/How-to-set-up/Unraid/

example of my *ars folder structure and docker compose on unraid:
(what I've done to get it working on unraid in the past)

Docker compose plugin...

First a bath script to make the necessary folders... Assuming default

#!/bin/bash
set -Eeuo pipefail

# =========================================
# Prepare *arrs folder tree for bind mounts
# =========================================
# Edit these to match your system
PUID="0"             # 99 Unraid 'nobody' user 0 root
PGID="0"            # 100 Unraid 'users' group 0 root

# Root for app configs (per-app subfolders below)
APPDATA_ROOT="/mnt/user/appdata/arrs"

# Root for data (media + torrents live under here)
ARSDATA_ROOT="/mnt/user/arsdata"

# Which app config folders to create
APP_FOLDERS=(prowlarr sonarr radarr transmission watchtower)

# Data subtree (TRaSH layout)
DATA_DIRS=(
  "media"
  "media/tv"
  "media/movies"
  "torrents"
  "torrents/completed"
  "torrents/incomplete"
  "torrents/watch"
)


log(){ echo "[$(date +'%F %T')] $*"; }

mkown() {
  local path="$1"
  mkdir -p -- "$path"
  chown -R "$PUID:$PGID" "$path"
  chmod -R 777 "$path"
}

log "Creating appdata under: $APPDATA_ROOT"
for f in "${APP_FOLDERS[@]}"; do
  mkown "$APPDATA_ROOT/$f"
done

log "Creating data under: $ARSDATA_ROOT"
mkown "$ARSDATA_ROOT"
for d in "${DATA_DIRS[@]}"; do
  mkown "$ARSDATA_ROOT/$d"
done

log "Summary:"
log "  PUID: $PUID  PGID: $PGID
log "  APPDATA_ROOT: $APPDATA_ROOT"
log "  ARSDATA_ROOT: $ARSDATA_ROOT"
log "Done."

this way
/mnt/user/appdata/arrs will be our compose docker and env location for latter!!!

then eidt the stack env

ENV:

TZ=America/Chicago
PUID=0
PGID=0

# --- Unraid shares (simple) ---
APPDATA_ROOT=/mnt/user/appdata/arrs
ARSDATA_ROOT=/mnt/user/arsdata

compose file:

Compose:

#version: "3.9"
#unraid compse is v2 adn this version tag is ignored!

But I believe your isseus is with pre-existing data and configuration of the docker that is hard failing not some much inner docker network communication...

Thanks for the response. I may have solved this by switching to macvlan. Seems to be working now. I also deleted the app data configs and reinstalled.
