For me, this seems to have been a case of VPN server misconfiguration going unnoticed until the recent fixes. Just in case you're in a position where somebody else is responsible for the server, or there's a different etiology, checking IPv6 [+] use this connection only for resources on its network (as suggested by darkk) also works for me.
