can't connect self-hosted vault with Android App

[Catskan-zz]

Hi all,

I have my personal Bitwarden server in my Synology with Docker and it works perfectly.

I just have a Xiaomi MI 9 and it's my first time in Android OS.
So, I installed Bitwarden Android App, change the server with my Self-hosted server (https://my.server:customport) and I can't connect to my Vault.

I tried with Firefox browser and Chrome (in my android) and the connection works.

In the application, I have "there is a problem connecting to the server".

Before, I had the Bitwarden iOS app and I never had a problem.

I use 1&1(ionos) certificate when I installed my bitwarden server.

I don't understand ...

In android, I have to set something ?

Thanks you for your help.

Regards

Android has stricter SSL requirements. Check your cert for issues here: https://www.digicert.com/help/

Here is results of the digicert check :

So, is a problem with the intermediate certificate ? How can I setting up this certificate in bitwarden ?

I am not sure. I would try contacting your certificate provider for help.

My certificate provider is ionos.com
The web page on the ssl certificate https://www.ionos.com/security/ssl-certificate

I have a domain in .fr with all of certificate ssl.

How can I help you ?

Hi kspearrin,

Have you any news for this problem ? Have you need others informations ?

I think that you already post your problem in the digicert check: The server is not sending the required intermediate certificate

I don't remember where I read this but Android needs a full chain certificate to work.

You can try with Let's Encrypt and see that this works with the full chain.

Hi,

I installed my certificates into Android directly and Bitwarden app works now.

Thanks for your help !
