I have re-installed WordPress via softaculous due to not

I have re-installed WordPress via softaculous due to not being able to login anymore with my previous site. I thought it was the quickest and easiest way to delete the website and to start again. However, after re-installing wordpress and going to wp-admin to login, it again will not allow me to login. It is sending me to a re-direct: https://sitename.eu/wp-login.php?redirect_to=https%3A%2F%2Fsitename.eu%2Fwp-admin%2F&reauth=1
Help, desperately needed on this one. Why is this happening? Why can I not log-in to my newly installed wordpress site?
