wp-admin pages redirect to external page

Newbie here.
Reinstalled wp several times from scratch
Debug log not showing nothing special

– Can’t install or even find themes: show this error text:

Ha ocurrido un error inesperado. Puede que algo vaya mal con WordPress.org o la configuración de este servidor. Si sigues teniendo problemas, por favor, prueba en los foros de soporte.

Sorry Spanish, “error unexpected, something went wrong with WP.org or the server. Check the forums…”
– Can’t update, install or find widgets : keep going to maintenance o blank page
– Some times when click on any of the Widgets/themes button, the page goes outside word-press and shows something like this:
bad page
