--rpc-bind-ipv6-address appears to be broken #10307
Description
Testing with 0.18.4.3 on OpenBSD 7.8:
monero-wallet-rpc --rpc-use-ipv6 --rpc-bind-port 6780 --rpc-bind-ipv6-address [fd:55::5e]
I've tried with and without the brackets, and the behavior is the same.

It binds on the IPv6 socket correctly.
nero# netstat -f inet6 -l | grep 6780
tcp6 0 0 fd:55::5e.6780 *.* LISTEN
But closes the connection for any HTTP call.

Does not do this with IPv4.
