  connect() to [2a05:d01c:a35:2902:6e18:7290:ff27:e9aa]:18444 failed:
  Cannot assign requested address (99)


My config:

bitcoind -printtoconsole -regtest=1 -rpcallowip=::/0 -rpcauth="...."


I'm running the node with through docker with the following image https://hub.docker.com/r/ruimarinho/bitcoin-core/

Thanks by advance for your answer.
First of all check that your system support IpV6.
Run this:

test -f /proc/net/if_inet6 &amp;&amp; echo "IPv6 supported" || echo "IPv6 not supported"


Then make sure to bind to ::ffff:0.0.0.0
