ipv6 support?

[645340633]

Hi.
I have installed node-red at hassos
My internet-provider use ds-lite which only use IPv6 to access from outside.
How can i access node-red with ipv6.
Normally ipv4 "199.0.0.1:1880" works
Example IPv6-adress is 1a0:2a02:9018:2221:5120:96d8:fb11:5815.
ipv6 "[21a0:2a02:9018:2221:5120:96d8:fb11:5815]:1880" does not work for access to node-red.
ipv6 "[21a0:2a02:9018:2221:5120:96d8:fb11:5815]:80" does work for access to web server.
It seems, that node-red does not listen to IPv6, only IPv4.
What and where do i have to adjust for solving the problem?
Thank's
greetings Uw
