Authentication error-credentials correct

Issue description:

I am setting up Symfonium with my Jellyfin server and I am receiving an “Authentication error. Wrong login or password.” message,

I know the credentials are correct because I am able to connect with other devices.

This is the log from Jellyfin. Private network firewall is turned off. I am a total noob to Jellyfin and I did search the forum prior to posting but could not find another user at this stage.
