Hello Warren,

Looking at the logs, you seem to be referencing a SSL certificate that's nowhere to be found:

nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/collabora.princelaw.com/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/collabora.princelaw.com/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)

As such, this is a local configuration problem so I'll mark the bug as invalid.

Regards,
Simon
