How does the credentials works when importing a database dump in Vaultwarden?

Hey guys 👋🏻 , posting this here and not in the issues page since I don't know if it's a bug exactly.

I'm trying to move my data from a Postgres instance (A) to another Postgres instance (B). I'm generating a database dump and importing it on the new database, and then set the DATABASE_URL env variable pointing to the B instance. The app starts correctly without any error, but when I try to login, I get this response:

{
    "error": "",
    "errorModel": {
        "message": "Username or password is incorrect. Try again",
        "object": "error"
    },
    "error_description": "",
    "exceptionMessage": null,
    "exceptionStackTrace": null,
    "innerExceptionMessage": null,
    "message": "Username or password is incorrect. Try again",
    "object": "error",
    "validationErrors": {
        "": [
            "Username or password is incorrect. Try again"
        ]
    }
}

From the logs:

[2025-01-27 15:09:19.011][vaultwarden::api::identity][ERROR] Username or password is incorrect. Try again. IP: <my_ip>. Username: <my_email>.

When I go to check the new instance, everything seems to be in order and exactly like the old instance.
In case this affects something, I'm currently running two instances:

https://vaultwarden.my-domain pointing to the A instance
https://v2.vaultwarden.my-domain pointing to the B instance

Could be the domain the issue here? That's the only difference between the two instances and I don't get why this couldn't be working as expected. Also if I attach https://v2.vaultwarden.my-domain to use instance A it works correctly

I have a similar issue, I have moved from sqlite to postgresql, after I finally got it working on my office laptop perfectly when running pgsql as backend, I tried it at home and then I exactly got this error, however my password cannot be wrong by any case. When I try it by creating a new user, it works just fine with this password, however I will not have access to my saved passwords anymore, therefore I tried to change the user_uuid for the passwords and out of a sudden I cannot access my account anymore, with the same password...

edit: Vaultwarden seems to have a problem with passwords at all... I can login to vaultwarden on one device but on not other devices...

Hey! Apparently when doing a backup you also need to make a copy of your /data folder, not just the database.

You can take a look on this:

It's not working for me even I'm following these steps 🤷🏻‍♂️

Hey @BlackDex 👋🏻 Sorry to tag you here. Any hint of what could be the problem here? I'm following the wiki (https://github.com/dani-garcia/vaultwarden/wiki/Backing-up-your-vault#restoring-backup-data) but it doesn't seems to be working. It's being a blocker for me
