> Hello,
> I have confirmed that on guacamole versions newer than 1.5.3 the WOL feature is not working properly. Specifically the WOL packet is not sent, and the connection times out after about 10s despite having set a longer time (screenshot attached).
> Checking "guacd" it does provide the below entries:
> {code:java}

> It shows an issue with "websocket" but it's seems a red herring as I am not connecting through a Proxy and without setting WOL, it works with no issues.
> The workaround I have found is using version 1.5.3 (for the supported architecture, which excludes ARM).
