Port already in use

[T_Jamess]

Like the description says, after installing jellyfin on fedora using the command on the website, running the jellyfin command shows me gives me a bunch of errors saying that 0.0.0.0:8096 is already in use. I previously dual booted with this laptop and had a windows install with jellyfin on a different ssd but I'm not sure how that's affecting it now that that ssd isn't even installed. The errors:

Jellyfin normally runs as a service. So you do not need to type in Jellyfin in the terminal, that's starting it twice, hence the error message. All you should need to do now, is run the startup wizard: http://localhost:8096
