coTURN service won't start after system startup

The coTURN service fails to start after the system startup and I had to check and start it manually in cockpit.

There was a (different) fix for this issue included in FreedomBox 22.4:

Do you also have the following settings?

listening-ip = ::
listening-ip = ::1

Yes these settings were included in my installation (Freedombox 22.7). The error persisted. Only the solution above solved it for me…
