This is machine translation I checked IPv6 as you said, and connected with IPv6 address, but the connection was unavailable. You can connect with IPv6 address or AAAA domain name, I don't know what is wrong. Rutview uses IPv6 to connect to the server, it crashes, and there is no information about failure.
This is machine translation The InternetIdService.exe program does not listen on the IPv6 port, and IPv6 cannot connect to the server. Please solve this problem. I have downloaded server2.9.b1.exe but the same.
