Login issue

Hello Efficient_Good_5784,

thank you for your fast response. First to your last point: No, I did not transfer anything from the "native" Jellyfin installation to the Docker container. I've used Jellyfin only as a media player for my own created small videos / timelapse movies on the Synology DS. There is no "individual" content in Jellyfin from me - at least not until today. 

Second to your first point: Please find the first screenshot of the Container Details in Portainer for the upper part. Perhaps you have already hit the problem: The "data" folder points to "config" - that doesn't seem right, does it? The question for me is now: How can I change this?

Via "Container Inspect" in Portainer I find some kind of configuration file - please find second screenshot (again the upper part). Here I find the following entry:

<"JELLYFIN_DATA_DIR=/config",>

I guess, the value "config" needs to be changes to "data", right? If so, how is the name of this file and where do I find it?

So if this perhaps already the problem and it's solution, I would wait with uploading any log files a minute. 

Thanks again.

Well, I've changed from <"JELLYFIN_DATA_DIR=/config",> to <"JELLYFIN_DATA_DIR=/config/data",> but that doesn't help. Would have been too easy. I've changed the value back to the "original" entry.

I attached a log-File from Portainer and the two screenshots of the further pages with the Container Details for Jellyfin. In the log-File, I have replaced my IP address.

The startup looks fine, but it looks like a clean slate startup. No libraries watched, etc.

Clear your browser cache, if that doesn't work you can make sure that the startup wizard is enabled so you can recreate the admin log.

In container path /config/config/system.xml there will be a line called "IsStartupWizardComplete". If that is true then set it to false and restart jellyfin.

I already changed that parameter from true to false in the system.xml. I think, you mean this command line:

<IsStartupWizardCompleted>false</IsStartupWizardCompleted>

I cleared the cache in Firefox, restarted Jellyfin and entered the IP-Address:8096 again. LogIn page comes up, but no login possible.

I also entered this URL: http://<IP-Address>:8096/web/?#/wizardstart.html
The blue circle is turning continuously - no entries possible.

Well, finally I solved the problem by stopping the Jellyfin container and deinstalling it. I also checked via console, that all files from the previously installed "native" Jellyfin app on the Diskstation were removed. After that, I executed a clean installation of Jellyfin with Docker/Portainer and now it works. Just in case, somebody else has the same problem.

Kind regards,
