Tom,
You've not given a lot of detail about your environment, however it's
possible that one or more system/container auto-updated something that
has resulted in what you see here.
If it were me I'd have a look to see what updates have occurred between
the time when the system was working, 'till it wasn't. This might assist
you to focus on relevant areas.
Other than that, this thread might add further insight:

FWIW I turn off auto-updates. Too many times I've had something
magically break overnight...

Hi all,
I've been using Guacamole/Guacd almost daily for months and months now
with zero issues, but today the containers have started failing to
connect to eachother and I can't figure out why. I've changed quite
literally nothing as the setup has been working great. As the containers
weren't working today, I stopped and removed them, then re-ran the
docker-compose (settings untouched) to recreate the containers. I've
since tried both 'latest' and specifying 1.4.0 images and neither seem
to work. I've verified the VM I'm trying to connect to is both alive and
acessible remotely via RDP directly.
I've also tried removing SSL and it still seems to fail:
[http-nio-8080-exec-1] ERROR o.a.g.s.GuacamoleHTTPTunnelServlet -
HTTP tunnel request failed: javax.net.ssl.SSLHandshakeException:

guacd[7]: ERROR: Guacamole protocol violation. Perhaps the
version of guacamole-client is incompatible with this version of guacd?
