Surprise. QBitorrent "updates" and fails to work again. DHT 0 Nodes

[reemusk]

Literally worked with 0 issues on 3.2.0, green icon, DHT had 300+ nodes, downloads did not stall.

Now, after the upgrade, magically, no connections. No errors in logs, port forwarding is still listed correctly in the router settings.

Restarted machine, double checked all settings, and of course, nothing is changed on my system except going to 3.2 to 3.3.

OSX 10.11.1 and QBitorrent 3.3.0

is IPv6 enabled in options/preferences?

As final solution perhaps; possible to do a clean installation and see if it does work correctly?

I would always advice to do a clean installation (if possible) when a big update like this is released.

Look at your logs. If it says that it listening to "127.0.0.1" then that means you had configured an invalid(or deleted) network interface. The begining of the log will indicate the exact reason.
Up until v3.2.5 if the interface was missing, qbt would happily connect to "Any interface" and that is why you didn't notice. That is a huge security hole. Now, if something is wrong with the configured interface it listens to 127.0.0.1 aka localhost.
(I cannot tell it to not listen to something).

Your log says it didn't find an IPv4 local address on the interface you have configured in the settings. So either try to configure it to use "Any interface" or enable "Listen on IPv6 address" for your specific interface.
