SOLVED: remote jellyfin Jellyfin.Api.Auth.CustomAuthenticationHandler problem

[ahmad]

i have a jellyfin in a docker container with domian and cloudflare for remote access when watching a movie or a show after some time it stop playing and can't do anything in the webpage and after refresh i got this first image, so i have to close the tab re-enter the domian for it and login again
