so, you started it from the command line and it works fine?
try to comment out the listener line and restart the mosquitto service.
I don’t know what is the root-cause… just trying out stuff 
This is showing exited though?

and it dies by itself after some (4) hours? strange…
I started it around 4pm yesterday, it died around 3am.
Its now 8.39am
no clue what could be wrong… i checked https://github.com/eclipse/mosquitto/issues but I didn’t find anything relevant… 
very odd damn!!!
Looks like it keeps happening around the same time
odd
saw this in the log:

Can anyone help diagnose whats occuring at that time?
could it be logrotate firing at 03:15 am causing the service to hang?
I don’t know… check your journalctl for messages around that time
Also… it could be due to the Halloween ! Ghosts are known to appear around 3 am ! (just joking 
)
hahah! Actually I think it was certbot restarting it!
Anyway, ive made some changes so ill see tomorrow if its stil working

Hi,
Picking up this issue has I have also troubles with Mosquitto since yesterday after apt-get update && upgrade.
Since then I can’t get Mosquitto up again.
This is what I get:
Blockquote
1560710587: Loading config file /etc/mosquitto/conf.d/mosquitto.conf
1560710587: mosquitto version 1.6.2 starting

1560710587: Opening ipv6 listen socket on port 8883.
1560710587: Error: Unsupported tls_version “tlsv1”.
That’s it then. The service doesn’t come up.
Any help would be appreciated!!
Thanks
Matthias
