Forum OpenACS Development: Re: can't connect to openacs.org port 80: network is unreachable
I believe the problem has another cause.
Hosting server doesn't support IPv6. That's why socketConnect fails on IPv6.
However, that wasn't supposed affect, once NS parameters are disabled since the beginning (i.e. within ns-config.tcl).
#set address_v6 ::1 ;# listen on loopback via IPv6
#set address_v6 ::0 ;# listen on all IPv6 addresses
Regarding your suspects on unclear reasons, it fails on IPv6 via port 443 (https)...
I guess the hardware, which hosts our VMs, doesn't support IPv6. I believe Patrick can tell us why.
Thus, as expected IPv4 works and IPv6 doesn't.
If IPv4 works why does ns_http request fail?
