AlertListener does not work with some hosts on Linux

[ReenigneArcher]

Describe the Bug

Plex alert listener fails to start on Linux (when using ipv6?) and the following error appears in the logs.

ERROR (alert:94) - getsockaddrarg: bad family

Expected Behavior

No response

Additional Context

IPv6 is likely disabled in Plex's python build.

We can possibly patch python-plexapi to setup websocket-client properly. https://github.com/ReenigneArcher/python-plexapi/blob/c41d98170b3761b8edc7d75970a01b80bb6281c6/plexapi/alert.py#L55

Getting this error, but I have ipv6 disabled everywhere. Running Plex on a Synology NAS, not under docker.

Themerr-plex 0.2.0

EDIT: same with running Plex on Mac OS

[ReenigneArcher]

@garlik82 I submitted a PR to address this in python plexapi, but unfortunately I don't think it will work in Python 2.7.

But yes, I now think it's an issue on (some) unix devices.

[garlik82]

No way around it then?

[ReenigneArcher]

Not at this time, but next version will not require the alert listener at least.

[garlik82]

Hit me up when you have a version to test. Thank you for your work.

[ReenigneArcher]

@garlik82 you can try nightly. Alert listener won't work but there is now a scheduled task option.

How do I trigger that task?

EDIT: nevermind

[garlik82]

I must be doing something wrong. I see no errors in the log but I also don't get any themes.

By next version you mean the next version of Themerr?

This can be fixed by using 127.0.0.1 instead of localhost as Plex's URL in plex_api_helper.py. The error comes from the fact that localhost resolves to ::1 by default on many Linux distros, but the WS API expects an IPv4-family address.

@zdimension Thanks for that info! I will put up a "fix" once plexapi is updated on pypi after pkkid/python-plexapi#1281.

I can confirm that this works. Awesome. Thank you.
