How many ports do you have configured for data connections? Every data connection (listings and transfers) uses a new port. Recommendation for the Passive port range is 100+ ports.
In case the listening port stops working, that should never happen. What exactly causes this I don't know, but it would have to be a very aggressive security software on your machine, if it blocks even localhost.
If you use a software like CurrentPorts, can you see the FZ Server service listening on the configured TCP port even after it stops responding?
