Hello, The function init_sock at pjlib-util/src/pjlib-util/resolver.c should check if the IPv6 is available instead of return an error. Regards, Alexei

Hi Alexei, Thank you for the report. The bug sounds valid, unfortunately I could not reproduce the issue on Windows 10 and Linux, have tried to manually disable IPv6 but still init_sock() did not fail (perhaps IPv6 loopback interface is still up). So I am afraid we'd need some more help to test the attached patch, thanks again in advance.

I can test. I ran into this issue yesterday. If it's the same error, it happened for me when the name server returned a normal response for the A record but a SERVER FAIL response for the AAAA record. In this case we got "dns not working" failures from pjproject. On Tue, Aug 16, 2016 at 12:45 AM, Nanang Izzuddin <nanang@pjsip.org> wrote: > Hi Alexei, > > Thank you for the report.

Hi Alexei, Finally have managed to reproduce the issue and test the patch here, the patch seems to work, so just checked in it (with slight modification) to SVN trunk for ticket https://trac.pjsip.org/repos/ticket/1953.

Hi George, Perhaps your case is not related to this issue, please also check ticket #1953 for more detail.

Hi Alexei, Thanks for the confirmation on the patch. Also just updated pj_dump_config() as suggested in SVN trunk r5421.
