Android Bitwarden app will not connect to Vaultwarden anymore

Hello community!

I have Vaultwarden running on my Start9. Updated version.
I am connecting via Tor.
The interface address works from the Tor browser.
I have orbot installed, and Bitwarden is selected as app to use Tor.
Orbot is connected.
I tried first with the .onion interface adress with only http://, did not fin server.
Tried than with the https:// and I get an error message Saying:

This has worked on my phone before, but stop syncing some time ago.

What do I do to get my Android Phone to work with my Vaultwarden Vault?
Is there a better way?
I have a Root CA from Start9 System, I use to connect over LAN, on my local network, but I do not think I have had to install any Certificate in Bitwarden before.

All I want is for it to work…

Thanks to anyone that can help.

I’d try two things.

  • Uninstall Bitwarden and delete the root CA
  • Trust the root CA again, then install Bitwarden
