Context

When trying to launch guacamole through CAPE it results in the error message displayed above. In the logs I don't see CAPE opening a guacamole session.

I am able to connect to a running VM through the guacamole setup outside of cape using the method as described in the docs (detailed under Additional Information)

Additional information

Outside of CAPE I run the VM, and get the encoded string for the VM and through a browser I can access the VM through guacamole with the connection established in the logs

Python script

>>> from uuid import uuid3, NAMESPACE_DNS
>>> from base64 import urlsafe_b64encode as ub64enc
>>> sid = uuid3(NAMESPACE_DNS, "0000").hex[:16]
>>> ip = "10.32.2.120" # Example 192.168.2.2
>>> vm_name = "win10x1" # example win10
>>> sd = ub64enc(f"{sid}|{vm_name}|{ip}".encode("utf8")).decode("utf8")
>>> print(sd)

Last summer I did have the interactive session working with Guacamole 1.4 (as described in ticket https://github.com/kevoreilly/CAPEv2/issues/1508), I have just rebuilt the server to get the latest updates

Your help would be appreciated, thank you
