Cannot change URL to https

I tried to change the url using ghost config, but I am not able to do it.

I had installed my ghost instance using bitnami in google cloud.

I tried doing the below.

Run ghost config set url https://www.missfrankierose.com and then ghost restart to configure Ghost properly.

the output I got is

ghost config set url https://www.missfrankierose.com
Working directory is not a recognizable Ghost installation.
Run ghost config set again within a folder where Ghost was installed with Ghost-CLI.

can anyone say me the exact location I should run this command?

Thanks

Maybe try the bitnam config tool?

While trying to change the domain name in bitnami conf my routes are not working…

sudo /opt/bitnami/apps/ghost/bnconfig --machine_hostname https://www.frankierose.com

i don’t get any error in console but when I try to load the page it says

cannot GET/

also I figured out that when I try to change my domain using config URL the domain is not getting changed.

is there anyway I can change my config file manually.

Thanks…
