I get exactly the same error.

@frknkrc44 @sdfg2 Can you please provide a screenshot of the preferences page (or better a browser devtool logs of the request). This would be really helpful :)

[sdfg2]

@SamantazFox what settings do you want in the screenshot? It does it no matter what preferences I choose.

I had a look in the console and inspector and couldn't find anything you might be interested in, happy to help if you can direct me (Vivaldi).

Same problem here on a fresh installation plus host, when setting anything and then confirming.

Works however, when an account is created and when logged in.

[SamantazFox]

@sdfg2 when you are in the inspector, you have a tab called "network". In here, you can see all the requests that the browser sent to a website. Click on the html request to /preferences?referer=..., and copy the contents of the request tab. It will contain the data sent when you pressed "save".

Note: Make sure to open the inspector before pressing "save preferences"!

(the sreenshot is from Firefox, as I don't have Vivaldi on this PC, but all browser inspectors are similar)

[sdfg2]

@SamantazFox here you go

[SamantazFox]

@sdfg2 Thanks :) However, I can't reproduce the error with my version of Firefox... Will try with Vivavldi later.

@frknkrc44 @lyn1337 @sdfg2 can you please tell more about your setups?

• is your instance running on bare metal? If yes, what distro are you using (ubuntu, debian, arch, ...)? Or is it running in docker?
• Do you have a reverse proxy, and if yes, which one (nginx, lighttpd, apache, ...)?
• Can you also post your server's config.yml(Make sure to remove your database password before posting!!)?

I'd like as many infos as possible to try to reproduce your bug :)

PS: also make sure that your ad- or cookies-blocker is not interfering!

This really isn't helpful but I've encountered this error a few times. A refresh always fixes it though so I've never been able to consistently reproduce it.

@SamantazFox

VPS, Arch, nginx 1.19.10. Turned off UO, same behaviour. Cookies set to block third party (so if it's that, I have questions... ;) ) Probably makes no difference, but using postgres 13.2.

feed_threads: 1
db:
  user: kemal
  password: lolnope
  host: localhost
  port: 5432
  dbname: invidious
# alternatively, the database URL can be provided directly - if both are set then the latter takes precedence
# database_url: postgres://kemal:kemal@localhost:5432/invidious
full_refresh: false
registration_enabled: false
login_enabled: false
top_enabled: false
feed_menu: []
host_binding: 10.1.0.1
cookies: CONSENT=YES+
default_user_preferences:
  dark_mode: true
  comments: ["",""]
  local: true
  related_videos: false
  quality: dash

EDIT: Tried refreshing when the error comes up, it asks to confirm resubmission but results in the same error.

EDIT2: I'm the only one using this, and will be the only one using it (it's locked down so hard for outside access), all I wanted was a way to set dash quality to 'best'. I couldn't see how to do that by editing default_user_preferences, which would be my preferred way of doing it.

[SamantazFox]

@sdfg2 Thanks for the infos. I've tried with both your config.yml and a vivaldi browser, and I can't manage to reproduce the issue yet. I'll try to reproduce your whole server environment later (I don't have the time to install archlinux atm ^^)

[sdfg2]

@SamantazFox sorry it's been a busy few days. I didn't realise that had been fixed! I've taken that out, same behaviour. And I tested in Firefox as well, same behaviour.

[unixfox]

@sdfg2 is this fixed then?

[sdfg2]

@unixfox Not unless there's a release I've missed?
