Softether stopped working, giving error 403

[nelze]

I've been using Softether for years now as it's the only vpn that works in a site in Japan that I need to access. It lets me select a specific DDNS hostname and the site only works with a specific number of those. However, it stopped working and just gives an error 403 now. Even google doesn't work and gives the same error. It can't access any site - even reddit. I tried all the different VPN relay servers available and they all give the same error. Is there a way to fix it?

SoftEther has not stopped working but some VPN server IPs are rejected. Try another server or use a different site, eg:
- google is OK on vpn591814087.opengw.net [Kor]
- duckduckgo.com does not error with 403 on JP VPNs
