Android app cannot connect to self hosted server over Tailscale

SZ3RzL5bet3NeKVMOXUgLk7sNYP1InSHA8U7oDV commented 1 year ago

Steps To Reproduce

Setup tailscale on homelab and mobile, bitwarden.example.com points to homelab tailscale ip.
Setup self hosted bitwarden server at https://bitwarden.example.com:9099.
Mobile app sign in and sync works when both homelab and mobile is on the same wifi network.
Disconnect mobile from wifi and use LTE.
Try to sync the vault.

Expected Result

Sync should succeed.

Actual Result

Sync over tailscale when not on the same wifi network fails.

I am able to access https://bitwarden.example.com:9099 from the mobile browser, so it's not a connection issue.
Connecting laptop to mobile hotspot over LTE and syncing browser extension also works, so it seems to be an issue only with the mobile app.
Connecting the phone back to the wifi network (where homelab is) makes sync from the app work again. So it is an issue only when the phone is outside my local network.

Hi @sdht0,

I am unable to reproduce this issue, it has been escalated for further investigation. If you have more information that can help us, please add it below.

Thanks!

I've been able to reproduce this issue consistently.

The symptom is exactly the same: sync works with my home WiFi, but fails when using LTE/5G cellular connection.

I haven't tried syncing on other WiFi networks, but given I'm connecting to the server using a publicly resolvable hostname resolving to a Tailscale IP address, I think it should work on other WiFi.

I have multiple websites hosted behind multiple Tailscale IP addresses:

Plex: works in both browser and the Android app
qBittorrent: works in both browser and at least one third-party Android app
Bitwarden/Vaultwarden: works in the browser, but NOT the Android app
TiddlyWiki (hosted on the same IP address of Valtwarden): works in browser, no Android app to test

Version information in case it's useful:

Tailscale: 1.68.1
Vaultwarden: 2024.1.2

Reverse proxy setup from Caddy:

    *.example.com {
        log
        tls fullchain.pem privkey.pem
        header {
            Strict-Transport-Security max-age=31536000;
        }
        encode zstd gzip
        @bw host bw.example.com
        handle @bw {
            reverse_proxy bitwarden {
                header_up X-Real-IP {remote_host}
            }
        }

        @wiki host wiki.example.com
        handle @wiki {
            reverse_proxy wiki:8080
        }

        handle {
            abort
        }
    }

When the issue is reproduced (connect via LTE + Tailscale on), I cannot see any request in the Caddy access log when trying to refresh it in the Android app.

Here's some logcat, hopefully this would be useful:
