I am seeing the same issue, using Google Cloud VM. Why could it be?

[angristan]

I think this might be the error you get when ipv6 is disabled, you can check using sysctl net.ipv6.conf.all.disable_ipv6, it should be 0

[abuwho]

Yes, it seems to be already 0.

root@vpn-01:~# sysctl net.ipv6.conf.all.disable_ipv6
net.ipv6.conf.all.disable_ipv6 = 0
