@randradebbva :
Since you mentioned it was working earlier till 8th (you were able to access target earlier), So I would suggest :
1. Confirm you have target profiles assigned by Experience Cloud System administrators as explained very well by @MihneaD .
2. If still issue persists then -
a. Try incognito window of browser or clear your browser cache & cookies to make sure new changes reflect.
b. Try in another System
c. Try in different Network.
3. Are you facing the issue only accessing the target or with other solutions as well ?
