Not sure the client's running

[Paul_M]

There is something in the console app showing fah errors...

That's just a small excerpt - no idea what it means...

[calxalot]

Are you using http/https proxies?

[Paul_M]

I'm not sure what that means.
The browser is pointing at https...
That console dump appears to suggest that the service is starting and running for a fraction of a second and then stopping...

[calxalot]

Is the client log.txt empty?

[calxalot]

After a little searching, it seems xpcproxy is possibly both a part of macOS security and a bit of adware installed in multiple browsers.

[jonault]

I see that same notice about xpcproxy in launchd.log when fahclient starts. It's definitely part of MacOS, in /usr/libexec.

[jonault]

One thing that's different - I don't see that message about "deferred event: domain spawn response"; instead a couple lines down I see "job state = running". I did have a work unit already in progress that I stopped & restarted, though, so maybe that would explain the difference.
