 Hi Mohammad,
Thanks you for the reply. Below is the output of the command you sent:
sudo -u nova stat /etc/letsencrypt/live/<MY_CONTROLLER_FQDN>/fullchain.pem   File: /etc/letsencrypt/live/<MY_CONTROLLER_FQDN>/fullchain.pem  Size: 5616       Blocks: 16         IO Block: 4096   regular fileDevice: 802h/2050d Inode: 7340138     Links: 1Access: (0644/-rw-r--r--)  Uid: (    0/    root)   Gid: (    0/    root)Access: 2021-06-04 15:47:48.544545426 +0100Modify: 2021-06-03 11:50:26.410071017 +0100Change: 2021-06-03 11:52:39.870554481 +0100 Birth: -
The permissions on the live directory are:
ls -al /etc/letsencrypt/live/total 16drwx--x--x 3 root root 4096 Jun  3 11:53 .drwxr-xr-x 9 root root 4096 Jun  3 11:50 ..-rw-r--r-- 1 root root  740 Jun  3 11:50 READMEdrwxr-xr-x 2 root root 4096 Jun  3 11:50 <MY_CONTROLLER_FQDN>
I changed the owner and group to nova as a test to see if that was the issue but it still didn't work. The first error I had was as you say a permissions issue on the live directory and as nova (su nova -s /bin/bash) I couldn't access that directory so I changed the permissions and tested it as the nova user (cd /etc/letsencrypt/live & cat fullchain.pem) and I could read the files in there. I then had the error I sent in the original email.
The funny thing is I had a test deploy and it all worked fine but when I redeployed it on new machines with the same OS (ubuntu 20.04) it won't work for me. 
Regards,Derek

 Hi Derek,

What's the permissions of the letsencrypt cert files and the user that
Nova is running on?

sudo -u nova stat /etc/letsencrypt/live/ <MY_CONTROLLER_FQDN>/fullchain.pem

Will probably fail, so you might wanna fix that!

I have secured horizon with letsencrypt certs (for now) and again all is fine. When I did a test deploy I also used those certs to load the novnc console securely and it worked.
