Mosquitto broker does not refresh SSL certs

[JeffFaer]

Describe the issue you are experiencing

I connect to my mosquitto broker with SSL on port 8883. Apparently my mosquitto broker was running for a while (and I don't monitor my cron jobs particularly well) because today I noticed that they were failing due to the SSL cert being expired back on January 24th.

I use the DuckDNS add on to automatically refresh the SSL certs, and I was able to confirm that the certs currently in the ssl directory are valid until May.

Restarting the mosquitto broker fixes this problem.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Which add-on are you reporting an issue with?

Mosquitto broker

What is the version of the add-on?

6.4.0

Steps to reproduce the issue

1. Set up the DuckDNS add on to create SSL certs
2. Set up the Mosquitto Broker add on to use the SSL certs that DuckDNS manages
3. Check when the SSL certs are set to expire
4. Run the Mosquitto Broker
5. Wait until the certs expire
6. Observe that SSL connections to the Mosquitto broker no longer work

Anything in the Supervisor logs that might be useful for us?

Anything in the add-on logs that might be useful for us?

Unfortunately I already restarted my add on :(

Is there a good way for me to recover logs from a previous run?
