I don't have any firewalls, antivirus, VPN etc. installed. Only native Windows firewall. To check if the problem is exclusive to my home computer, I just installed AS 1.3.2.7 on my friend's computer. Another computer, other installed programs (Kaspersky Internet Security), another ISP. But the problem is the same! Unable to login to Rakuten. Perhaps I am the only person in Poland who uses AS, since no one else is reporting a problem.
