I have an instance of magento 2.2.5 running on an AWS lightsail instance. Things were hit and miss for a while trying to get everything working, but at one point yesterday I did have the site up and functional with one exception. The site would redirect from my domain name to the public IP address. After some digging I determined that it was because I had not assigned a static IP address in lightsail. I did that, and then the domain address stopped working completely. More searching led me to believe that I needed to update the server name (e.g., which I did successfully). As soon as I did that however, the admin login stopped working. I get the "you've logged in incorrectly or your account is disabled" error. I've tried the various suggested fixes for this, such as changing the user password, clearing site cookies, etc., but nothing seems to work so I suspect it has something to do with the server name update. Maybe something else needed to happen in conjunction with that? Other than the admin login the site appears to work okay, but I haven't tried creating a user account yet. Advice?
