Moving WordPress from subdomain to main domain

I was developing new version of webpage on WordPress on subdomain dev.astroprava.cz (there was not WordPress before) and now I moved the files to main domain https://www.astropraha.cz. But now if I want to sign to WordPress admin it redirects me to dev.astropraha.cz/wp-login and there is 404 error.
What can I do to fix it, please?
