Remove `local_address` from your config.

This system doesn't provide enough entropy to quickly generate high-quality random numbers.
Installing the rng-utils/rng-tools, jitterentropy or haveged packages may help.
On virtualized Linux environments, also consider using virtio-rng.
The service will not start until enough entropy has been collected.
