Hello @Juan ramon_Jimenez ci9872,

Thank you for your message. 

Are you using Windows?  If so, frequently it is the Windows firewall blocking connexions to Adobe. Try resetting the firewall and see if that fixes it.  If not (or if you are using another operating system), please try another browser as a test and see if that works.

If neither of these solve the problem, please tell us your operating system and browser and the version numbers.

Thanks,
