Hi @ancieque ,

I’m pretty sure you have the same issue than this other community post: [iOS mobile app Sign in fails - #10 by \_jc](https://community.passbolt.com/t/ios-mobile-app-sign-in-fails/4793/10)

Connect yourself your docker container and run this command:

```auto
gpg --show-keys /etc/passbolt/gpg/serverkey.asc

```

It should output only one result. We got some customers with docker installation where this command return multiple results.

If you get more than one entity, delete the server keys:

```auto
rm /etc/passbolt/gpg/serverkey.asc
rm /etc/passbolt/gpg/serverkey_private.asc

```

And restart your container. New proper keys will be generated.

Your users will get this warning:

Just accept the new key and you should be able to use the app.

I assume it is an old bug who has been fixed.

Relevant documentation: [Passbolt Help | How to rotate server GPG keys](https://help.passbolt.com/faq/hosting/how-to-rotate-server-gpg-keys)

Let me know,

Best,
