iOS App Login Fails with "An error occurred"

[YannisAm]

Setup:

• Vaultwarden: Running the latest version as a Docker container on my home server
• iOS App: Latest version installed
• iOS Version: Up to date
• Nginx: Running on the same LXC container as Vaultwarden (Proxmox environment)

Problem:

When trying to log in through the iOS app, I receive the error message: "An error occurred". However, I can successfully log in via:

• The Firefox browser extension
• The web interface

Steps Taken:

• Cleared app data and reinstalled the iOS app
• Pulled the latest Vaultwarden Docker image and restarted the container

Despite these steps, the issue persists.
Logs:

[2025-03-31 17:35:08.360][start][INFO] Rocket has launched from http://0.0.0.0:80
[2025-03-31 17:35:56.962][request][INFO] GET /notifications/hub?access_token=eyJ0eXAiOiJKV1QiL
[2025-03-31 17:35:56.963][response][INFO] (web_files) GET /<p..> [10] => 404 Not Found

It looks like there’s a 404 Not Found error when the app tries to reach /notifications/hub.

Could this be an issue with WebSocket connections or Nginx configuration? Any insights would be appreciated!

Same here. Additionally, I have the following error:

and the reverse proxy is configured in the following way:

Anyone has any solution?

EDIT: it seem to be somehow related to the https configuration, as pointing the vault directly to an internal LAN IP works without any issue. Given my setup, I am ok leaving as is, but i believe it requires some kind of investigation.
