Login endless authentication loop

[KenQB]

I have an endless loop of login authenitcation requests from my nexcloud server which runs here in my freedombox server. When I click grant access it ways I am in and can close the window but then apparently logs me out. I have had this problem in the past from time to time but haven’t been able to sort out how to make it go away. What am I doing wrong?

The Basics

• Nextcloud Server version (e.g., 29.x.x):
  • **[Nextcloud Hub 10 (31.0.7)
• Operating system and version (e.g., Ubuntu 24.04):
  • replace me
• Web server and version (e.g, Apache 2.4.25):
  • Debian GNU/Linux 13 (trixie) and FreedomBox version 25.9.3.
• Reverse proxy and version _(e.g. nginx 1.27.2)
  • don’t know
• PHP version (e.g, 8.3):
  • don’t know
• Is this the first time you’ve seen this error? (Yes / No):
  • No
• When did this problem seem to first start?
  • It has happened off and on over the last few months
• Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
  • Freedombox
• Are you using CloudfIare, mod_security, or similar? (Yes / No)
  • no, my own server

Never had this, issue, but as a workaround, you might want to try login with an app password.

Also, to enable people to help you, you should provide the following information:

• Which version of the client you are using
• Which operating system you are using (it says Debian in the screenshot, so which version?)
• Which desktop environment you are using
• Which installation method you are using (apt from the Debian repos, apt from a third-party repo, AppImage, Flatpak, Snap)
• Which browser you are using

Oh, I’m not sure if that’s what’s causing the issue, but if you’re already logged in to another account or on another server in this browser, log out from that account first before trying to set up a new account.

Your config and logs would also be helpful, since you posted none of that and deleted those sections from your report for some reason.
