I just bought F-secure Total, I've seen the payment go trough and the email have been activated.
However when I try to log in I get an error page :
Any of you have an idea on how to fix this ?
I guess it could be a browser issue. Have you tried with a different browser? I know it works in Internet Explorer and Firefox. You could try going to the main F-Secure home page - here in the UK it's: https://www.f-secure.com/en_GB/welcome then navigate to My F-Secure from there. Otherwise, I'm not sure what else to suggest, other than a Support Ticket.
The usual SAFE login page is here: https://mysafe.f-secure.com/portal/welcome
The same problems happens again when I try from this URL.
I too could not connect to my.f-secure.com using Chrome. I had allowed all cookies for that site in Win10, opened the Win10 firewall to that site, and added that site as an exception in Chrome.
Seeing the message above, I used Firefox instead and was able to log in and extend my subscription.
But after that, Firefox could no longer log in:
"The connection to my.f-secure.com was interrupted while the page was loading.
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified."
