Postgresql error in the chirpstack docker

Is this problem solved?
I have the same issue when using the chirpstack docker.
So when running the “docker-compose up”, I encountered the following log and I can not access the application server web page via 8080 port.
What I am wrong?

ping PostgreSQL database error, will retry in 2s" error=“dial tcp: lookup postgresql on 127.0.0.11:53: no such host”

Did you wait for a while? Does it start working after a minute?

I don’t know what’s in your docker-compose file. But the official example describes two errors that may occur in the logs, which should go away after some time.

Thank you for your kind reply.

I have found the cause of this problem, so the PostgreSQL was not started properly when running the docker-compose up.
There was a problem in the old Raspberry Pi OS, I used Raspberry Pi OS 10.
After updating it into 11 (bullseye), this problem has been removed itself. :grinning:
