I’m guessing that you don’t have this change in your kobo-docker:
I’d be afraid to attempt an upgrade right now, but in kobo-docker/nginx/docker-entrypoint.d/30-init-kobo-nginx.sh, you could try manually changing container_ports=( ['kpi']='8000' ['kobocat']='8000' ) to container_ports=( ['kpi']='8000' ['kobocat']='8001' ).
Edit: after doing that, you’ll need to recreate your NGINX container, e.g. with ./run.py -cf up -d --force-recreate nginx
If that doesn’t work, send me the commit of kobo-docker that you have. You can get this by going into the kobo-docker directory and running git show.
