Cannot login on LAN, wrong password?

[Unravelled]

Hello!

My apologies in advance if this has been asked but I could find nothing relating to my issue and I've been at this for several days

The issue I'm running into is I keep getting a 'Invalid username or password. Please try again.' error when trying to login via the static IP I assigned the host, 192.168.1.138, in my router. I have tried the 'reset password' option but no json file is generated that I can find. I'm able to login to my server on the computer hosting it and I can get the login screen on devices connected to the lan.

I have deleted then rebuilt the container several times, but it feels as if the 192 address is leading to a completely different instance of Jellyfin, though I don't know how it would as I've not installed it outside of Docker.

I'm currently running Zorin OS (fresh install), have a Jellyfin container through Docker Desktop with the portainer extension. I'm also running a VPN but this issue persists regardless if it's on or not. For reference,  I followed along with the tutorial at How to Install Jellyfin on Docker with Portainer - YouTube

I am admittedly new to Linux and more so Docker, but I'm gaining a lot of knowledge through trying to troubleshoot this lol

Can anyone point me in the right direction?

I'm assuming you did the part of the tutorial where you mounted /config to a host volume?

If so, stop your container and then go to that folder and find /config/system.xml. Open the file to edit and near the top will be "IsStartupWizardComplete". Change that from true to false. Save, close, start the container. Open your browser and navigate to your Jellyfin server. It will go through the initial setup again, including recreate the admin account. When you get to the steps for the library it will already be populated with your existing libraries. Just click next until you get to the end.

I did as you suggested and it still came back with a login screen. On the off chance I forgot I installed jellyfin, I used

Code:

sudo apt remove jellyfin

but it's not installed

That apt command wouldn't do anything since you've been running Jellyfin in a container.

Without knowing more about your setup or what steps you did or didn't do from the tutorial, it's hard to provide guidance. Can you show me screenshots of the portainer UI for the Jellyfin container?

I appreciate you taking the time to help me try and figure this out but I've resolved the issue! After I posted, I think a light bulb went off somewhere.

I found that I installed Docker and created a jellyfin container prior to using Docker Desktop. I completely removed Docker/Desktop (https://askubuntu.com/questions/935569/h...all-docker) and then reinstalled Desktop, followed by the container. I can now access it via my lan connected devices!

I hope this serves as a good reference for someone in the future XD
