Server Version#: 1.19.3.2852-219a9974e Player Version#: Problem: Beginning recently I cannot login to the web player using Firefox anymore, when accessing through localhost (127.0.0.1) or local network. Symptom: - When opening web app’s homepage, a progress wheel briefly shows before the page redirects to `app.plex.tv/auth/`, - Upon signing in through the auth portal, the page navigates back to local server, before redirecting to `app.plex.tv/auth/` again, this time saying “There was an error signing in” - This will repeat forever. Platforms and software tried: - PMS on macOS (1.19.3.2852) and Raspbian (Raspberry Pi) (1.19.3.2764) - Firefox on macOS (76.0.1, latest) and Raspbian (68.8.0esr) - Unaffected: Other browsers, such as Chrome, Safari, and Firefox on iOS. - Unaffected: Other methods to access PMS, such as through mobile app, and `app.plex.tv` - **Unaffected: Firefox Developer Edition (77.0b9, latest)** (this makes it seem like a Firefox issue) Attempts to fix: - Logging out and then logging in again; logging in using another Plex account - Clearing browser cache, clearing website data for `plex.tv`, `localhost`, and `127.0.0.1` domain, using Private mode, disabling Firefox’s Enhanced Tracking Protection - Removing PMS preferences and reinstalling PMS I’ve seen a few topics on this issue now. Any help to fix, hints on troubleshooting, where to find logs, etc. are greatly appreciated. Thanks! ---

Hi, i have the same problem but the linked-to solution does not work for me (either does not exist or is private). Is there a way for me to get access to that thread, or find the content if it no longer exist? best regards ---

I also have this problem on Firefox running on Ubuntu if it matters. I assume my credentials have expired and it is not redirecting to login page. ---
