Yeah, my bad, I didn't want to break it again after fixing it, but I can see there'd be value in documenting this. In my case, I saw the following error popping up in my `nifi-app.log` when trying to run bin/cli.sh nifi current-user: WARN [NiFi Web Server-363] o.a.nifi.web.server.HostHeaderHandler Request host header [example.com] different from web hostname [127.0.0.1(:8444)]. Overriding to [127.0.0.1:8444/nifi-api/flow/current-user] So what I did was add example.com to the nifi.web.proxy.host config, which fixed the issue for me. It would be really helpful if the error message in that case would state the error more clearly. The current error looks like the CLI isn't handling the response correctly, although it's actually a server error. So I guess the CLI is in fact not handling the response properly. (Unrelated: It'd be nice to be able to insert <code> tags to make this more readable. They're currently being stripped when you press "Post") 🙂

My bad, apparently. I found errors in logs that made it clear that this was a bad configuration.

I'm able to run cli.sh registry commands, but not cli.sh nifi commands for some reason. They're both secured and use the same props files (except for different baseurls) as defined in ~/.nifi-cli.config:
$ cat ~/.nifi-cli.config
nifi.reg.props=/appl/nifi-registry/nifi-registry-current/conf/cli-props
nifi.props=/appl/nifi/nifi-current/conf/cli-props
$ ./bin/cli.sh registry list-buckets

But nifi commands fail:

Does anyone have any idea what's going on? Happy to provide more debugging output.
I'm running Nifi 1.9.2 and Nifi-Registry 0.5.0.
