no route to host to PostgreSQL

[laengu]

Description

Hello All
I tried to get the Synapse container in my docker environment running.
But it always stops with the log entry:
"psycopg2.OperationalError: connection to server at "postgresql" (192.168.1.29), port 5432 failed: No route to host"

I use a bridged macvlan network, the settings look good and docker inspect network shows everything is good.
I have 23 other containers running fine on this network.
I checked the PostgreSQL before because I had the same problem with another container and it that it accepts connections.
So it is not PostgreSQL and it is not the network configuration.
Further troubleshooting showed that the Synapse container is not accepting the gateway configuration it receives from the network.

Can somebody have a look why that might be?

Steps to reproduce

using a bridget macvlan network

Homeserver

homeserver

Synapse Version

latest

Installation Method

Docker (matrixdotorg/synapse)

Database

PostgreSQL

Workers

Single process

Platform

QNAP NAS with bond network and using bridged macvlan network.

Configuration

nothing special, all standard

Relevant log output

"psycopg2.OperationalError: connection to server at "postgresql" (192.168.1.29), port 5432 failed: No route to host"

Anything else that would be useful to know?

I am an IT engineer.

This feels like a networking problem specific to your setup, not particularly related to Synapse. Could you maybe check in the #synapse:matrix.org for help troubleshooting?
