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: {code:java} guacd[1]: INFO: Creating new client for protocol "rdp" guacd[1]: INFO: Connection ID is "$f41f9319-154b-4c58-9b9c-3d9fd6995046" guacd[16]: INFO: Security mode: Negotiate (ANY) guacd[16]: INFO: Resize method: display-update guacd[16]: INFO: Clipboard line ending normalization: Preserve (none) guacd[16]: INFO: User "@6ec7067c-b91e-43b3-80b0-2fbeb9d7bb36" joined connection "$f41f9319-154b-4c58-9b9c-3d9fd6995046" (1 users now present) guacd[16]: INFO: Local system reports 4 processor(s) are available. guacd[16]: INFO: Graphical updates will be encoded using 4 worker thread(s). guacd[16]: INFO: Loading keymap "base" guacd[16]: INFO: Loading keymap "ja-jp-qwerty" guacd[16]: WARNING: Ignoring requested color depth of 16 bpp, as the RDP Graphics Pipeline requires 32 bpp. guacd[16]: INFO: RDP server closed/refused connection: Server refused connection (wrong security type?) guacd[16]: INFO: User "@6ec7067c-b91e-43b3-80b0-2fbeb9d7bb36" disconnected (0 users remain) guacd[16]: INFO: Last user of connection "$f41f9319-154b-4c58-9b9c-3d9fd6995046" disconnected guacd[1]: INFO: Connection "$f41f9319-154b-4c58-9b9c-3d9fd6995046" removed. {code} and "guacamole" this one: {code:java} 21:03:32.450 [http-nio-8080-exec-8] INFO o.a.g.event.EventLoggingListener - User "*****" (authenticated by "postgresql") successfully authenticated from 192.168.10.156 21:04:12.231 [http-nio-8080-exec-7] INFO o.a.g.tunnel.TunnelRequestService - User "*****" connected to connection "11".

Duration: 9124 milliseconds {code} 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). Regards -- This message was sent by Atlassian Jira (v8.20.10#820010)
