> Hello,
> I have confirmed that on guacamole version newer than 1.5.3 the WOL feature is not working. Specifically the WOL packet is not sent, and the connection times out after 10s despite to have set a longer time (screenshot attached).
> Checking the logs "guacd" provided the below messages:
>

> It does show an issue with "Websocket" but it's not related as I am not using a Proxy and without using WOL it works with no issues.
>
> The workaround is using version 1.5.4 (for the supported architecture).
