Failed to connect to database

Hello. I just installed Komodo v2 on OpenWrt 25.12.1 running on NanoPi R6S. I went with the FerretDB option and followed the installation instructions to a tee. For some reason, the FerretDB container is not starting:

root@OpenWrt:/opt/komodo# docker ps -a

Any idea what could be the issue?

Maybe postgres fails to start, check logs, usually folder permission issue

Hi @burdulixda, please check if you already have another port running or if you made a mistake in the environment variables, also if you have been able to resolve it, kindly provide a feedback and close the issue.
