[Help Wanted] Invalid password / Unknown error when trying to login

[tg5hKVHPyX]

Describe the issue
Since September or October of last year, I'm no longer able to log in to my account. It's a free account on the official instance if that matters. This started happening since I wiped my phone which was the only device I was successfully logged in on, and trying to login from the web app gives me the same errors since then. I get an "Invalid password" error and now more recently, I've gotten an "Unknown error" when trying to log in. I'm certain that there's no problem with the password as I use a password manager and haven't changed the password since creating the account. I really need to access this account and back up the notes from it, there's a lot of important stuff on there. I've contacted the help email and they told me there's nothing they can do since accounts can't be restored, but I don't want to give up. Has anyone else had this same problem?

To Reproduce
Steps to reproduce the behavior:

1. Go to sign in.
2. Enter email and password.
3. Click enter.
4. See error.

Expected behavior
Successful login to my account, like I used to be able to.

Smartphone (please complete the following information):

• Device: Samsung A70
• OS: Android 10
• Browser: Firefox
• Version: the error started happening since last October, current version is 111.1.1
• Also using the latest version of the app that's released on f-droid which is 3.150.37

There's sadly very little anyone can do without the correct password. Is it possible that you used another email address, if you're certain about the password being correct?

When I reached out to [email protected], the person replying confirmed that an account with my email address does exist. So I am sure that both the email and password are correct.
