This is as far as I got, but I am not properly authenticated.
The program is below.
The error I get is:
File "/home/frans/lxd/websock.py", line 42, in <module>

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

Obviously something wrong with certificates, but what ?
Anyone a clue?
Thanks, Frans
