Login screen shows "Invalid username or password" for all users despite using the correct passwords

Situation
My AWS EC2 instance of OpenEMR Express Plus is no longer allowing any of the users to login longer. Instead it only shows the “Invalid username or password” error message. Both I and the nurse practitioner know we are using our correct passwords. I suspect it may have something to do with the password expiring since I deployed the instance on AWS Cloud servers back in early March and it is now nearing the end of October. However, I do not know what I need to access and how to access it to change any line of code to allow us to sign in again (reset the timeframe for password reset, etc.). Unfortunately, I need into this instance without deleting any data stored on it as we have used it already and need that documentation. Urgently if possible as some of the data is needed as soon as I can have access to it. Any help navigating this issue would be greatly appreciated.

It seems the ones who resolved it were using a different setup for server deployment and maintenance that I am.

Logs
Did you check the logs? If someone could assist me in finding the logs, I will post them in a comment. It seems AWS needs the instance to be deployed with specific settings to allow logs to store in the CloudWatch logs and I must have not set that up correctly because no logs are stored there.
Was there anything pertinent in them?

I’m not a dev but I’ve seen this problem happens all the time. OpenEMR needs to have a better system for expired password. Check into this post: Resetting user passwords through database
