Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).

- Use reverse proxy provided by my Keenetic router, according to logs it seems to be nginx, but cannot detect its’ version
- PHP version (e.g, 8.3):
- 8.3.19
- Is this the first time you’ve seen this error? (Yes / No):
- Yes
- When did this problem seem to first start?
- After updating from 30 to 31
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)

Summary of the issue you are facing:
When I click “log in” in web interface (when connected with DNS name), it throws me back to login screen without any messages. Logging in from local network with server local IP works as intended. Also I can log in via other apps, such as Celeste sync client or Thunderbird (not sure about other apps I use, I’m affraid to log out as now they function well).
I tested two fresh containers - one with NC30 and another with NC31. Problem appears only on second container.
Steps to replicate it (hint: details matter!):
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
Every time I try to log in, I see this message in logs:

This happens even if I turn off bruteforce protection by setting auth.bruteforce.protection.enabled false in config.php
Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
Nothing relevant
Console gives some warnings. There’s common one both for my main instance, which is affected with issue, and for fresh test container with Nextcloud 30, which works for me. I marked warnings, specific to problematic instance with [!]:

What’s about network tab, it shows that all components (mainly stylesheet and couple of JS scripts) are loaded successfully with code 200. I saved all to HAR, which gives more complex information, but it’s impossible to attach file here or paste text from it.

Configuration

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
