wintrmute 0 Posted November 29, 2016 Posted November 29, 2016 (edited) I've found a bug in Emby. If the server is busy running a big media scan (eg. due to recent new setup) then logins fail, with errors logged about the database being locked. Emby version: 3.1.239~beta-1728.1 OS version: Ubuntu 16.04 LTS EDIT: Actually, even after the media scan finished (after 45 minutes), I still received the same errors when trying to log in. Restarting the emby-server service fixed it though. Still, not a good first experience on a new install. 2016-11-29 14:08:16.2498 Info HttpServer: HTTP POST http://10.23.1.1:8096/emby/Users/authenticatebyname.
