The bnconfig part was tested previously
I have also disabled the bnconfig part as per the instructions about renaming the host/hostname and that has been done properly too...
The content of the configuration file /opt/bitnami/apps/canvaslms/htdocs/config/domain.yml is as follows;
_test : _
domain : localhost
domain : "localhost:3000"
### whether this instance of canvas is served over ssl (https) or not
###defaults to true for production, false for test/development
### filesdomain: "canvasfiles.example.com"_
if you have any ideas/updates please inform
as this is getting really strange now
I can get to the domain but the images are coming back with an internal server address still...

So... the issue here was the final line in the config.
sudo chmod +t /tmp
after I did this, it fixed the remainder of the issues, thankyou for your forbearance and help where possible, most appreciated team.
