POSSIBLE PROBLEMS AND POSSIBLE SOLUTIONS

weird behaviour on old Python versions

The main deployment of this software uses a relatively current version of Python (take a look at Dockerfile to see which one).

If you experience weird bugs (especially encoding-related ones) while using an older version of Python, please file an issue and try to use a newer version of Python.

can't bind to socket

Labello tries to bind itself to :: by default. This means it will respond to all requests regardless of the client's ip address, the used network interface or the used version of the internet protocol.

On some systems this might fail. Please file an issue in this case. If you get an error message stating something like socket.gaierror: [Errno -9] Address family for hostname not supported on startup, you can try to set SERVER_ADDRESS to 0.0.0.0 in the config file. This should restore the old behaviour and just listen on IPv4.
