Do you have IPV6 setup done on your machine? I wanted to test RM5582 - Cannot SSH tunnel over IPv6 with identity file but unable to do so. I had even tried to create the global IPV6 address which is not accessible across the VM (neither Windows nor Ubuntu even after setting up radvd).
Even my internet service provider does not provide the global address (only link-local address). For now, I have suggested the author of the issue to test from his end. But to verify from our side, can you give some thought on this?
