[HELP (Not Launching/ Crashing)] Trainer detected but won't connect

[elParaguayo]

Checklist

• I have given details of my install including Distribution, Wayland/ XOrg, Parameters Used, echo $XAUTHORITY, etc.
• I have provided logs showing any errors, if available (use VERBOSITY=3 ZWIFT_FG=1 zwift)
• I have filled out the issue template to the best of my ability.
• This issue only contains 1 issue (if you have multiple issues, open one issue for each issue).
• This issue is not a duplicate issue of previous issue.

Describe the issue

First off, thanks for your work on this. I'm new to Zwift and would love to have this running on my laptop.

The issue I'm facing is that, when trying to connect devices via the Companion App, Zwift shows them as "Connecting..." but never "Connected.".

I have a JetBlack Victory trainer but the error seems different to #234

Distribution Details

I'm running Arch Linux, qtile window manager with the wayland backend (so I'm running with xwayland). EDIT: I've tested on qtile's X11 backend and get the same behaviour.

Linux my_username-laptop 7.0.13-arch1-1 #1 SMP PREEMPT_DYNAMIC Tue, 23 Jun 2026 11:14:21 +0000 x86_64 GNU/Linux

My ~/.config/zwift/config file is just:

ZWIFT_WORKOUT_DIR="$(xdg-user-dir DOCUMENTS)/Zwift/Workouts"
ZWIFT_LOG_DIR="$(xdg-user-dir DOCUMENTS)/Zwift/Logs"
ZWIFT_SCREENSHOTS_DIR="$(xdg-user-dir PICTURES)/Zwift"
NETWORKING="host"
ZWIFT_OVERRIDE_GRAPHICS="1"
CONTAINER_EXTRA_ARGS=(-e XCURSOR_SIZE=48)
DONT_PULL="1"

XAUTHORITY is not set.

Reproduction steps

1. Open Zwift Companion
2. Start Zwift
3. Select "Pair with phone"
4. Click on device
5. Select trainer
6. Device never connects
   ...
