HTTP lister failing with IPv6 addresses #1705

Open mpanwar-github opened 2 years ago

mpanwar-github commented 2 years ago

I am trying to use IPv6 address with http listener but giving below error.

Starting listener at url.http://[fe80::a3fe:944b:534f:7ec%enp24s0f1]:8585 terminate called after throwing an instance of 'web::uri_exception' what(): Invalid hexadecimal digit

And used lookback address as wel.

While using address as "http://[::1]:8585"

terminate called after throwing an instance of 'boost::wrapexceptboost::system::system_error' what(): resolve: Service not found

Your response will be much appreciated.

huh, in the first case it looks like we fall over on scopes, the second might be some other issue.

Can it bind to the default interface "[::]" or perhaps "[::]/128"?

barcharcraz commented 2 years ago

obviously that's not a workaround, but I have seen instances (esp on linux) where the loopback interface is not assigned the normal address because of configuration issues. I know you're on linux (or maybe mac/bsd) because windows scopes are numeric. Actually enp24s0f1 looks like a systemd "predictable name" so you're probably on linux.
