Maybe your problem is something else altogether. Looking at your log:
*2024-01-24T20:11:37.072480+01:00 homeserver guacd[3080072]: Unable to read file "/" *2024-01-24T20:11:37.403365+01:00 homeserver guacd[3080072]: RDP server closed/refused connection: Security negotiation failed (wrong security type?) 2024-01-24T20:11:37.072480+01:00 homeserver guacd[3080072]: Unable to read file "/" 2024-01-24T20:11:37.403365+01:00 homeserver guacd[3080072]: RDP server closed/refused connection: Security negotiation failed (wrong security type?) This is a problem that I believe I have seen in the past where freerdp requires to write something on the guacd server filesystem. Without this, freerdp cannot properly connect to any server. This is an issue I have seen before on the list and the archive should have detailed instructions. If my memory serves me correctly, what you have to do is be sure that the user that is running guacd on the server has write permissions on the root filesystem of the guacamole installation. If you are running it as a "root" which you should not, you will have to figure out what is that runtime location. What I do remember is that if you run guacd as a NON ROOT user, the directory you set as the home directory of the guacamole user is used to run the daemon. Hopefully this *may* solve your issue.
