Hi Nick, Following up on my previous email regarding the "remote server is currently unavailable" error in Guacamole.
I've extracted the following trace from the Docker container. I'm still trying to understand why the disconnection occurred and why the remote desktop server became unavailable. I also checked the targeted Windows instance, and its event logs indicate the disconnection was initiated by the Guacamole client. *Aug 8 14:14:41 b9febc5c10ba[1471]: guacd[123102]: DEBUG:#011Ignoring unsupported clipboard data.
