When I try to log into my Android app using my Plex credentials, I get “User Can Not Be Authenticated”. But when I select “Sign in with browser” it works, and then I’m good to go in the app. What’s the hiccup here? I’m authenticated fine in the Plex app, just not the PlexAmp app.

Thanks. Attached. Just to add to the info, this was happening when I’m at home on my own network and also on mobile data away from home. ckronengold_Log_124927202372278.zip (49.9 KB)

Apologies for the delay, I was on vacation. Nov 15, 2025 16:28:31.428 [0x537e8500] DEBUG - Networking: Completed request 89: (POST https://plex.tv/api/v2/users/signin?login=xxx&password=<token>) with code 401 (have 175 bytes) in 91 ms. It looks like you’re using the wrong password :sweat_smile:

I don’t understand. I can log in using the exact same credentials into the browser. And I’m using a password manager, so I’m not entering the info incorrectly. It also happens when I log in via Google. What login is using the wrong password?

The Plexamp log shows you trying to sign in with an incorrect password, as best I can tell. It’s possible there’s some weird character encoding issue if it’s indeed the correct password?

almost certainly some networking issue between Plexamp and plex.tv with your device in the middle. you can upload Plexamp logs after attempting to log in.
