After updating to the latest version of RocketChat, I can't login

[Anonymity1234]

I am having this error "User not found or incorrect password" after I updated my RocketChat hosted on DigitalOcean's droplet. My application wouldn't require the users to login to the chat, if they had the permission in the application generally, they could automatically be logged in RocketChat without ever having the need to put any credentials in the login page, instead the login page of RocketChat wouldn't show up at all.

Please, let me know how can I resolve this?

I looked and found that this problem has persisted for other people as well after making updates, but I couldn't really understand if they were able to fix it or not. I know some of them were talking about LDAP settings etc, I checked in my droplet's docker where I have installed RocketChat, and I don't have LDAP settings enabled.

I changed the admin's password through the container in MongoDB, but that still didn't help in logging in.

I would really appreciate if someone can help me get out of this problem.
