[BUG] - Unable to connect to specific device

[ac2323]

I am able to connect to all devices just fine except for this one. I get the following in the browser when trying to preview the desktop:

The docker container just gives this error: Desktop preview request for device cc62ef81-57f4-495a-9220-c9f11011bce2 and process 22848 failed: An error occurred while requesting desktop preview. dbug: Microsoft.AspNetCore.HttpOverrides.ForwardedHeadersMiddleware[1] Unknown proxy: 104.23.209.83:0

Trying to connect yields this error and no logs in browser console or Docker logs: An error occurred on the agent while creating remote control session.

Additional Context/Info

Running behind Cloudflare proxy. I noticed that "Unknown proxy:" error in the docker logs, but this occurs with the working devices as well so I'm not sure if it's related. I do have the Cloudflare cache bypass rule set up.
