Hi,

I am testing out 0.13.0-beta4 and seeing strange behaviour with relay servers.

note: i upgraded from 0.12 -\> 0.13 if that makes a difference

in my config its completely disabled however on running syncthing it connects to a relay server anyway:

```
[JEAQ4] 05:43:17 INFO: Joined relay relay://111.221.44.148:17602 [...]

```

config options as returned by rest/system/config:

```

      "default"
    ],

Confirmed, that’s a bug. I think the thing is that the new “default” listen address includes relays, but it should still follow the relaysEnabled or it should be deprecated…

Thanks for reporting it!

Might need some discussion on how to resolve in the cleanest manner. In the meantime, to _actually_ disable relaying, set your listen address to `tcp://0.0.0.0:22000` instead of `default`.

~10 year bump but is this still ongoing?

I have relay server disabled but openSnitch shows attempts are still being made regularly

Maybe it should be in the documentation or tied to switch automatically when Relay server is disabled?

As you can read in the linked bug, this issue was fixed almost 10 years ago.

The hostname `data.syncthing.net` is not used for relays, but it is used for usage reports. Your screenshot does not show whether usage reporting is enabled or disabled on your instance.

53/UDP (DNS) makes no sense as the service for [data.syncthing.net](http://data.syncthing.net) either, so no sure what that thing is reporting, really. DNS lookups for [data.syncthing.net](http://data.syncthing.net)?
