I am using reverse proxy (for SSL) so googling if this could have impact on the configuration and found this -> https://serverfault.com/questions/1098036/unable-to-access-wordpress-dashboard-with-nginx-reverse-proxy
in my case I had $_SERVER[‘HTTPS’]=’on’ at the end of wp-config.php file. It was essential to have working website.
BUT NOW! admin dashboard started to work when I moved the line ealier – right before: “That’s all, stop editing! Happy publishing.”
Thank you very much!
