Bitwarden iOS app not working with self-hosted Vaultwarden "An error has occurred"

Hey everyone! I am having issues with accessing my self-hosted Vaultwarden server from the Bitwarden iOS app.

I recently had to re-install the Bitwarden app and now I am unable to login to my instance. I am seeing the "An error has occurred" popup, once when I enter in my email address and hit Continue and then every time I enter my password, and I am unable to login to the vault.

The browser extensions and Mac app work fine and my password is not incorrect. These are the versions that I am running in my setup:

  • Vaultwarden 1.32.5
  • Web-Vault 2024.6.2c
  • iOS app version: 2024.11.0 (1680)

I am running Vaultwarden on a Raspberry Pi as a Docker container and running it through a Cloudflare Tunnel. I made sure there are no WAF rules or cert errors or anything causing the issues. Again, I am able to login and access my vault just fine in the Bitwarden browser extensions as well as the app for Mac.

Does anyone know what the issue might be? I am completely unable to access my vault from my iPhone. I have searched around GitHub/Reddit/etc and have seen this issue has become common lately but none of the suggested fixes I have tried worked (updating everything to the latest version, setting KDF iterations higher to 650,000, making sure container is using latest image, etc).

Any help is appreciated!! Thank you!
