Password Access Denied

I’ve had my node running for months. Now all of the sudden I can not log in via WinSCP or Putty either. I could with Supermon but that’s it. Access Denied!

I have many many times but no more. Says Incorrect password.
I have reset server, Pi , House breakers, I just can’t log in to change some settings.

I’m lost , do I need to redo Image on SD?

Possible corruption of the SD card. Can you hook it up to a monitor via HDMI and describe the output, preferably embed a screenshot here from your phone?
