Good morning, for some reason that I do not know I cannot enter the database for a long time, I did not touch anything and I do not know what could be happening, I also tried with different browsers and nothing attached captures
Did you read the error message? 
Did you tried to login with ssl/https?
Then I don’t have any idea. Probaly you can debug the issue a bit, check the login on your smartphone and so on. I’m not able to reproduce the issue on my systems which makes it nearly impossible to help you without accessing and debug your system directly - which I don’t want to do.
