this worked fine last week, today, on my laptop, the reverse proxy dies right away:

This app can't run on your PC
To find a version for your PC, check with the
software publisher.
i didn't change the compose file. Port 6379. i've checked Task Manager and htop and i can't find anything obvious. Is Docker keeping a ghost reservation?
ive already run docker compose down in teh project folder, restarted Docker Desktop and checked that no other termnial is running teh stack. the error comes back instantly every time. is there a command that just tells me who owns a port?
